	Opened ahead of schedule despite schedule challenges, the new ramp from Route 202 to !-76 speeds traffic towards Philadelphia.

American Infrastructure, of Worcester, PA recently completed the largest highway construction project ever awarded by the Pennsylvania Dept. of Transportation (PADOT). Located in King-of-Prussia, a busy commercial hub in Philadelphia's northwest suburbs, the Route 202/I-76/422 interchange project took three and one-half years to complete at a cost of $215 million.

Work began in the spring of 2000, by American Infrastructure's business unit, Allan A. Myers. It included the construction of 19 bridges, 12 retaining walls, and placement of 350,000 sq yd of concrete paving. "Remarkably, all work was performed in an area of not much more than one square mile and was accomplished with little disruption to the traffic," states Gerard Maurer, one of Myers' project managers."Extraordinary considerations were taken to accommodate traffic, so we had to be creative." Maurer credits co-project manager Tom Kinsman and general superintendent Phil Scala for keeping the project—and traffic—flowing smoothly.

	At about the one-third point in the project, the new highway network begins to take shape.

A new two-span 490-ft steel truss railroad bridge, for example, was completely constructed in an area adjacent to its eventual position over I-76. "We launched the bridge into place between midnight and five o'clock on a Sunday morning," says Maurer. "Monday morning commuters couldn't believe their eyes."

As on any large project, new challenges periodically arose, but none so daunting as the unusual geological conditions discovered after the excavation was underway. The project was bid with a contract allowance of 14, 400 cu ft for sinkhole repair, but excavation revealed the existence of more and more sinkholes as work progressed. In the end, more than 1.4 million cu ft of pressure-injected grout was pumped into the voids to stabilize the site. This delayed work by nearly a year, but an accelerated schedule was then negotiated between Allan A. Myers and PADOT.
