Construction Status: Summer 2019

Final Stage of Bridge Rehab Project This Summer

Summer 2019 — The final construction stage of the project to rehabilitate the U.S. 202 bridges over Amtrak at the U.S. 30/Exton Bypass Interchange in Chester County is underway following completion of work on the outer half of the southbound bridge.

Crews completed cleaning and re-painting the southbound bridge's steel I-beam superstructure and placed the concrete deck and outer parapets in late spring, completing the major bridge work on the $26.4 million project. Work then got underway to restore the median area in early summer.

With the southbound bridge work finished, the "express lane" is being removed and two lanes have been restored in each direction on the rebuilt northbound and southbound bridges. The final stage of the project will regrade the median, install guiderail, signs, etc. and mill and repave the approach to both the northbound and southbound bridges in work that is expected to be completed at night.  

Construction on Dunwoody Drive below the bridges to replace the retaining wall that supports the embankments under the bridge also finished in late summer. Rehabilitation of the deck, expansion joints, parapets and approaches on the Morstein Road bridge over U.S. 202, located south of the U.S. 30 interchange, has been completed.  

All work on this project is expected to be completed in late October.

Work on the southbound bridge followed the completion of rehabilitation of the northbound bridge in mid-2018.
bridge is rehabilitated a half-at-a-time.

Crews completed replacement of the deteriorated concrete pavement on the two-lane ramp from U.S. 30/Exton Bypass to U.S. 202 north in early December 2018. Replacement of the concrete pavement on the two-lane ramp from southbound U.S. 202 to U.S. 30 finished in late spring 2018.

PennDOT replaced the ramps' concrete 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 bridge and ramp repairs will complete the final phase of the U.S. 202 Section 300 improvement project in East Whiteland and West Whiteland townships, Chester County. Allan A. Myers Construction, of Worcester, PA, is the general contractor on the 100 percent federally-funded project.
