King of Prussia, PA – The ramp from southbound U.S. 202 to the U.S. 30/Exton Bypass and Business U.S. 30 in East Whiteland Township, Chester County, has reopened to two lanes following replacement of the deteriorated concrete in the pavement and in the sound wall foundations, the Pennsylvania Department of Transportation (PennDOT) announced today.
Crews removed the concrete construction barrier from the work area at the off-ramp overnight Wednesday, December 20, to open the right lane of the two-lane ramp early morning Thursday, December 21. The opening of the right lane marked completion of the first-of-two stages of concrete replacement on the two-lane ramp.
Removal and replacement of the ramp’s left lane pavement will be performed at night under temporary work zone traffic patterns beginning in early 2018 as weather permits. Those temporary patterns will be removed each morning by 5:00 AM to provide motorists two-lanes on the ramp during peak travel times.
Deteriorated concrete on the ramp from the eastbound U.S. 30/Exton Bypass to northbound U.S. 202 will be replaced later in 2018.
Construction began last spring to replace deteriorated concrete in the pavement and in the deteriorated sound wall foundations at the interchange, reducing the ramp to one lane instead of two where it exits southbound U.S. 202. The ramps provide access from southbound U.S. 202 to U.S. 30/Business and the U.S. 30/Exton Bypass.
PennDOT is replacing the pavement and sound wall foundations after discovering that the original concrete, placed during construction of the Exton Bypass during the mid-1990s, was deteriorating due to a chemical reaction between the concrete’s sand and cement known by engineers as ASR (alkali-silica reaction).
The concrete replacement operation is part of a $26.4 million project to complete the final phase of the U.S. 202 Section 300 improvement project, including the rehabilitation of two bridges over Amtrak rail lines and the eastbound U.S. 30/Exton Bypass ramp to northbound U.S. 202 in East and West Whiteland, Chester County.
Construction to rehabilitate the inside half of the northbound U.S. 202 bridge over Amtrak and the U.S. 30 ramp is expected to finish in early 2018. Rehabilitation of the outside half of the northbound bridge will begin immediately after northbound traffic is shifted onto the rehabilitated inside half of the span.
Allan A. Myers, Inc. of Worcester, Montgomery County, is the general contractor on the project which is financed with 100 percent federal funds.
