Roads and Bridges personnel are constantly working to keep County bridges and roads in good repair.
- Repairing our bridges. Montgomery County owns and maintains 131 bridges and culverts. The County has made it a priority to repair or replace all Structurally Deficient bridges in its inventory by 2026. To date, the County has cut its inventory of structurally deficient bridges from 53 (40%) in 2017 to 23 bridges (18%) today.
- Repairing our roads. Over the last five years, 75 miles of County-owned roads have been repaved. By end of 2023, Montgomery County expects to have resurfaced all 150 lane miles of County-owned roads. All current road projects now include high visibility epoxy paint applied to center lines, shoulders, and intersections markings to help keep travelers safe.
2023 Project Schedules
Ongoing Projects
Montgomery County's Roads and Bridges team works tirelessly to ensure the projects they take on are completed safely, on time and on budget. See below for a rundown of the projects they are currently overseeing.
This project consists of the maintenance, repair and other associated work at three (3) County-maintained bridges:
- County Bridge No. 73 – Swedesford Road over Wissahickon Creek, Upper Gwynedd Township and Lower Gwynedd Township. The scope of work at this location includes constructing rock protection along both abutments and pier, repointing the deteriorated stone masonry and rebuilding the damaged portions of the near left and far left wingwalls, and removing the sediment deposits along the near right bank. Update: In stream work at Bridge 73 has been completed and masonry work will be performed after Bridge 118 work has finished.
- County Bridge No. 118 – Keith Valley Road over Park Creek, Horsham Township. The scope of work at this location includes constructing rock protection along the abutments and pier and underpinning the pier, repointing the deteriorated stone masonry, rebuilding the damaged portions of the near left wingwall barrier, removing the sediment deposits and debris beneath Span 1, along the near abutment, and beneath Span 2 along the pier, and backfilling the scour holes throughout the channel in Span 2. Update: Work at Bridge 118 has started.
- County Bridge No. 295 – North Dietz Mill Road over Ridge Valley Creek, Salford Township. The scope of work at this location includes underpinning the far abutment and far left wing wall and constructing rock protection along the far abutment and far left wing wall.
All roads will remain open during construction. Flaggers will be present where necessary. As always, please use caution, expect delays and obey flaggers when traveling through active work zones.
Montgomery County Bridge 6, which carries Mill Creek Road over Mill Creek in Lower Merion Township, was closed in September 2021 due to severe undermining caused by the post-Hurricane Ida floodwaters. Posted detours will remain in place until the bridge is reconstructed. The demolition work is in progress and all overhead utilities have been temporarily relocated. This bridge is a two-phase construction project due to an active PECO gas main and an active Lower Merion Township sewer line, which will be relocated during phase 1 construction. The bridge is estimated to be completed in April 2024.
Montgomery County Bridge 101, which carries Old Gravel Pike over the Swamp Creek in Schwenksville, is a three-span stone masonry arch bridge that has been closed to traffic since 2010. The bridge is currently undergoing a rehabilitation to restore the structure for future use as a pedestrian bridge. The long-term vision for Bridge 101 is to be incorporated in the Swamp Creek Trail or Sunrise Mill Connector as those plans come to fruition. The rehabilitation project is scheduled to be completed by December 2023.
Montgomery County Bridge 99, which carries the Perkiomen Trail over the Perkiomen Creek between Gravel Pike (PA-29) and Deep Creek Road, is an eight-span stone masonry arch bridge that once carried Gravel Pike over the creek until the PA-29 bridge was constructed by PennDOT in the 1970s. This bridge is now part of the Perkiomen Creek Trail system near the entrance to Green Lane Park. It is currently being rehabilitated to ensure safety to pedestrians, cyclists and horseback riders on the trail. The design and construction will restore the bridge to its original, beautiful structure. This project is currently estimated to be completed in December 2023.
Montgomery County Bridge #84, which carries Price Road over Unami Creek in Marlborough Township, was closed in September 2021 due to severe damage caused by Hurricane Ida. Assessment of this bridge in coordination with the Federal Emergency Management Agency is ongoing.
The Ridge Pike Improvement Project involves the full reconstruction of Ridge Pike between Norristown and Philadelphia, with additional widening and safety improvements at specific locations. The project will lessen congestion, improve safety, improve stormwater management, provide safe areas for pedestrians, and help keep the adjacent communities economically competitive.
Please visit our dedicated Ridge Pike Project page for more details.
Construction will begin on Monday, March 6, to replace County bridge 177 to improve mobility and safety on Sterigere Street between Stanbridge Street and Harding Boulevard in the Municipality of Norristown, Montgomery County.
Under this contract, Montgomery County’s construction contractor will remove and replace the entire existing bridge structure and approaches over Stony Creek to allow for corridor and waterway improvements. This will eliminate the current weight posting of the bridge and improve safety along the corridor and waterway.
Motorists are advised of a road closure is scheduled on Sterigere Street between Stanbridge Street and Harding Boulevard for replacement of existing bridge through January 24. Please allow extra time when traveling through the area because backups and delays may occur. Due to the nature of construction and closure of the bridge, a detour has been established. Motorists will be directed to follow the posted detour route via Stanbridge Street, Marshall Street, Markley Street and Harding Boulevard.
Demolition of the existing bridge structure has begun and a temporary Pedestrian Bridge has been erected to help maintain the walkability of the area.
Completed Projects
Montgomery County's Roads and Bridges team takes tremendous pride in helping our residents and visitors reach their destinations safely and efficiently. See below for an look at some of the most recent projects they've completed.
All new striping has been completed for the section of Germantown Pike stretching from Swede Road to Trooper Road in East Norriton and Worchester Townships. This completes the mill and overlay work for this stretch of roadway.
Montgomery County Bridge #163, which carries Lutheran Road over the Minister Creek in New Hanover, was originally constructed in 1923 as a single lane, two-span, continuous concrete slab bridge spanning 38 feet. An August 2016 inspection of the bridge resulted in an overall poor rating and the bridge was listed as structurally deficient and in need of replacement. The Engineering design contract was awarded to Bergmann Associates of Conshohocken, PA. As of August 2019, the bridge was inspected again and reported to be in need of high priority maintenance items per the PennDOT Bridge Safety Inspection Manual. The bridge inspections were subsequently scheduled at shorter time intervals. In April of 2020, the Engineering design, permitting, and environmental studies were completed and ready to be advertised for construction bids.
The new bridge was designed to be a precast concrete box culvert with a clear span of 30 feet. The Construction contract was awarded to Richard E. Pierson Construction of Malvern, PA with a start date of April 28, 2022. The project was scheduled to be completed within 182 calendar days and reopened to traffic by October 27, 2022. With oversight by Michael Baker International of Fort Washington, PA providing Construction Inspection and Quality Control services, the bridge was completed and opened to traffic on August 20, 2022, which was 68 calendar days ahead of schedule and just in time for school openings and subsequent bus traffic.

All milling work has been completed as of April 3, 2023. All paving work was completed as of April 12, 2023. Please note, some areas may still require line striping.
Montgomery County Bridge 296, which carries Rostkowski Road over the Ridge Valley Creek in Green Lane, was originally constructed in 1922 as a 51-feet long, two-span, concrete T-beam bridge. This two-lane bridge was reconstructed in 1989. As of 2018, the bridge was inspected and found to be in an overall poor condition and designated as needing replacement. The Engineering Design contract was awarded to Alfred Benesch & Company of Pottsville, PA, which began the arduous task of securing permitting and legal right-of-way, performing surveying and geological testing, conducting environmental studies, and reviewing roadway design alternatives among many other details.
The final Engineering Design was completed in November 2021. The new bridge was designed to be a single-span, pre-stressed concrete box beam structure with two lanes of traffic and widened shoulders. The Construction contract was awarded to H&K Group of Skippack, PA with a start date of January 10, 2022. The project was to be completed within 210 calendar days and reopened to traffic by August 8, 2022. With oversight by McTish, Kunkel & Associates of Allentown, PA providing Construction Inspection and Quality Control services, the bridge was completed and reopened to traffic on July 5, 2022, which was 32 calendar days ahead of schedule.
Bridge 77, which carries Plymouth Road over the Wissahickon Creek in Lower Gwynedd Township, was originally constructed in 1839 as a two-span, stone arch masonry bridge. This two-lane bridge was reconstructed in 1914 and again in 1977. As of 2018, the bridge was inspected and found to be in an overall poor condition and designated as needing replacement. The Engineering Design contract was awarded to Whitney, Bailey, Cox, and Magnani of Baltimore, MD, which began the arduous task of designing and permitting the bridge construction.
The final Engineering Design was completed in November 2021. The new bridge was designed to be a single-span, pre-stressed concrete box beam structure with two lanes of traffic and widened shoulders. The structure was designed to have a 71’ 6” span length with two 11’ wide travel lanes and widened shoulders to accommodate the Bicycle PA Route S. The bridge also features an architectural stone façade on the barrier walls. The Construction contract was awarded to Loftus Construction of Cinnaminson, NJ with a start date of April 4, 2022 and a completion period of 180 calendar days. The bridge was opened to traffic on October 21, 2022.
Our Bridge 162, which carries Stump Road over the Little Neshaminy Creek in Montgomery Township, was originally constructed in 1916 as a 28-feet long, single-span, concrete-encased Steel I-beam bridge. This two-lane bridge was widened in 1980 with reinforced concrete slabs. As of 2018, the bridge was inspected and found to be in an overall poor condition and designated as needing replacement. The Engineering Design contract was awarded to Larson Design Group, Inc. of Williamsport, PA, which began the arduous task of securing permitting and legal right-of-way, performing surveying and geological testing, conducting environmental studies, and reviewing roadway design alternatives among many other details.
The final Engineering Design was completed in October 2021. The new bridge was designed to be a single-span, pre-stressed concrete box beam structure supported on integral abutments. The structure was designed for two lanes of traffic with a full shoulder on the northbound lane and full width pedestrian sidewalk on the southbound lane. The Construction contract was awarded to R.E. Pierson of Pilesgrove, NJ with a start date of January 18, 2022 for utility relocation work. The bridge construction work started on April 28, 2022 with a scheduled completion date of November 27, 2022. With oversight by McTish, Kunkel & Associates of Allentown, PA providing Construction Inspection and Quality Control services, the bridge was completed and opened to traffic on November 23, 2022, just in time for the Thanksgiving Holiday weekend.
The Old Neiffer Road Bridge in Schwenksville, also known as the Sunrise Mill Bridge, has recently been completely rehabilitated after years of deterioration and severe damage from the post-Hurricane Ida floodwaters. Originally constructed in 1845, the bridge is part of the historic Sunrise Mill complex, which contains buildings dating to 1767. The bridge is a four-arch, stone masonry structure, which carried Old Neiffer Road over the Swamp Creek, and was last rehabilitated in 1967. The bridge was closed to traffic when the Neiffer Road Bridge was constructed by PennDOT further downstream. The Old Neiffer Road Bridge will now become a trail connector from the complex to the future Swamp Creek Trail.
The Sunrise Mill Bridge rehabilitation Engineering contract was awarded to Gannett-Fleming of Audubon, PA. The project was in the design phase in 2020 and was scheduled for construction in the summer of 2021. However, the remnants of Hurricane Ida dropped upwards of 8 inches of rain in Montgomery County in a 24-hour period on September 2, 2021. The Swamp Creek, swollen beyond capacity due to the storm surge, reached a level that overtopped the bridge. The surging floodwaters caused significant damage to the structure including a collapse of the downstream barrier wall and arch ring, bulging of the abutment wingwall, and significant loss of stones across the entire bridge.
The construction work began in January, 2022. The project was awarded to Loftus Construction of Cinnaminson, NJ with oversight and inspection services provided by McTish, Kunkel and Associates of Allentown, PA. The process of rehabilitating a stone arch masonry bridge requires the placement of arch centering, or shoring, equipment, and the dismantling and reconstruction of the bridge elements. During this work, the area was hit with another significant rain event on April 8, 2022. Once again, the Swamp Creek was elevated to a near 10-year flood level. The storm surge, coupled with upstream debris from the winter months, caused a damming effect at the construction site, which eventually gave way and damaged the structure further.
Despite this significant setback of additional damage and lost equipment, the construction resumed almost immediately. The structure was in danger of suffering an arch collapse, but the construction team worked quickly to repair the pier damage and strengthen the arches over the next few weeks.
By July 2022, the bridge was beginning to resemble its original look. The arches had been rebuilt and the stonework on the spandrel walls was nearing completion. Through the good fortune of consecutive dry months, the construction continued uninterrupted. The arch centering supports were removed and the construction focus was on the barrier walls and bridge deck surface. Stone masonry work and repointing continued throughout the project until Loftus Construction successfully completed the rehabilitation of the Sunrise Mill Bridge on September 8, 2022. The following photo shows the finished product from the downstream view. Many thanks go out to the team that brought this beautiful structure back to its former glory, including: the Loftus Construction team, McTish-Kunkel & Associates, Gannett-Fleming and many representatives of Montgomery County that made it possible.
Bridge 166, which carries Swamp Pike Bridge in New Hanover Township, reopened to traffic on October 25, 2022.
