PennDOT Completes Major Construction to Rehabilitate U.S. 202 Bridges over Amtrak in Chester County

King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) has completed the final phase of the U.S. 202 Section 300 improvement project, which includes the rehabilitation of two U.S. 202 bridges over Amtrak rail lines in East Whiteland and West Whiteland townships, Chester County.

PennDOT recently completed work that began in early 2017 to rehabilitate northbound and southbound U.S. 202 bridges over Amtrak and repave several ramps connecting U.S. 202 with the U.S. 30/Exton Bypass under the $30.1 million Section 3RR contract.

Under this project, PennDOT’s contractor repaired the six-span twin structures by upgrading the support piers; replaced the bridge decks and walls; constructed a retaining wall to stabilize the embankment under the bridges; rehabilitated existing concrete pavement north of the bridges; and installed new Intelligent Transportation System (ITS) equipment.

In addition to rehabilitating the two U.S. 202 bridges, the project included restoring U.S. 202 pavement near the U.S. 30 Interchange; rehabilitating the bridge carrying Morstein Road over U.S. 202 in East Goshen Township; and installing new highway signs and Dynamic Message System (DMS) structures on U.S. 202 and U.S. 30 in Chester County and Montgomery County.

With work on the project substantially completed, post-construction “punch list” items that are temperature-sensitive will be completed on the undersides of the bridges next spring. These operations are expected to have no impact on traffic.

Allan A Myers, Inc. of Worcester, Montgomery County, is the general contractor on the Section 3RR project, which is financed with 100 percent federal funds.

The completion of the Section 3RR project marks the end of more than 14 years of construction under the Section 300 contracts to widen and improve nearly seven miles of U.S. 202 in Chester County from the Route 252 (Swedesford Road) interchange in Tredyffrin Township to just south of the U.S. 30/Exton Bypass exit in East Whiteland and West Whiteland townships.

Section 300 construction began in May 2005 on the $13.7 million Section 3IT contract for installation of traffic cameras, electronic message signs, traffic monitoring equipment, and other Intelligent Transportation Systems (ITS) components on U.S. 202, the U.S. 30/Exton Bypass and Route 100. The contract, which concluded in June 2010, also included installation of fiber optic lines connecting the equipment to PennDOT’s regional Traffic Control Center in King of Prussia.

In 2007, construction began on the Section 310 and Section 311 contracts to replace six bridges over the expressway between the Route 252 (Swedesford Road) and Route 401 interchanges. The bridges were replaced with longer structures to provide room to widen the expressway under the spans. Overhead bridge construction ended in mid-2010.

In early 2011, work began on the Section 320 contract, which rebuilt and widened four miles of U.S. 202 to three through-lanes in each direction from Route 252 (Swedesford Road) through the Route 29/Great Valley interchanges. The Section 320 contract also improved Route 29/Morehall Road and Swedesford Road surface streets and intersections in the vicinity of the expressway; erected sound barrier walls along both sides of U.S. 202; and rebuilt and improved the Route 29/Great Valley Interchange, adding a two-lane northbound collector-distributor road to separate through traffic from traffic exiting and entering U.S. 202 at the busy complex of ramps. Section 320 construction ended in late 2014.

In spring 2013, the Section 330 contract began, which upgraded and widened an additional 2.5 miles from just south of Route 29/Great Valley through the Route 401 Interchange, which also was reconstructed. Route 401 (Conestoga Road) and Swedesford Road were widened and improved at the interchange, and noise barrier walls were installed at eligible locations in the project area. Construction on Section 330 was completed in fall 2016.
