Construction Status: Fall 2017

Deck placement this fall on northbound bridge, pavement replacement continues on southbound ramp to U.S. 30

Construction crews this fall will finish cleaning and refurbishing the steel superstructure on the inside half of the northbound U.S. 202 bridge at the southern end of the U.S. 30 Interchange in Chester County in preparation for placing the new concrete deck later this year.

Rehabilitation of the superstructure is taking place on both the top side of the steel beams and on the underside, where the structural components, including the connections between the steel and the support piers, are replaced or refurbished.

Northbound U.S. 202 traffic remains two lanes wide through the work area. The inside lane splits off into an “express lane" pattern utilizing the southbound bridge through the work zone. The outside lane remains on the northbound side, providing access to the U.S. 30 off-ramp and rejoining the inside “express lane” on the north side of the work area.

Crews also have replaced the deteriorated concrete pavement from the outside lane of the ramp from U.S. 202 south to the westbound U.S. 30 Exton Bypass. Work continues this fall to replace the deteriorated concrete foundation wall that supports the noise wall panels along the ramp. The sound wall panels, which were removed for replacement of the foundation wall, will be replaced once the new wall cures.

Traffic will be shifted later this year onto the outside ramp lane and work will then get underway to replace the deteriorated concrete pavement on the inside ramp lane. During all remaining work on the southbound ramp, the ramp's approach will remain one lane-wide.

Construction also will begin this fall on Dunwoody Drive below the bridge to build retaining walls to support the bridge's southern abutments. 

The work is taking place under the first of four construction stages* of the $26.4 million contract that will complete the final phase of the U.S. 202 Section 300 improvement project by rehabilitating two U.S. 202 bridges over Amtrak rail lines and the eastbound U.S. 30 Exton Bypass ramp in East Whiteland and West Whiteland townships, Chester County. (*Bridge and ramp construction is being done under project stages 3A, 3B, 4A, 4B.)

Under the 100 percent federally-funded project, PennDOT is rehabilitating and re-decking the deteriorated northbound and southbound U.S. 202 bridges, constructing a retaining wall on Dunwoody Drive to support the bridges’ southern abutments, installing and upgrading electronic message signs along the U.S. 202 corridor, and replacing the deteriorated concrete pavement on the U.S. 202 ramps to and from the U.S. 30/ Exton Bypass.

One northbound "express lane" has been shifted onto the southbound bridge. The other northbound lane remains on the northbound side behind construction barrier while the inside half of the bridge is rebuilt. Once half of the bridge is rebuilt, the single lane will be shifted onto the rebuilt side behind barrier while the other half of the span is rebuilt. When one bridge is finished, the pattern is reversed, with three lanes placed on the new bridge while the southbound bridge is rebuilt in halves. ((The project is scheduled for completion in late 2019. Allan A. Myers Construction, Worcester, PA, is the general contractor.
