The I-476 Improvement Project

The Pennsylvania Department of Transportation (PennDOT) is moving forward on its three-phase program to upgrade and improve its portion of I-476 between I-95 and the Pennsylvania Turnpike (I-276) Mid-County Toll Plaza in Delaware and Montgomery counties. Collectively known as the I-476 Improvement Project, PennDOT's projects are designed to prolong the life of I-476 and improve overall ride quality. With one construction project completed in 2005, two upcoming projects will be phased and carefully staged to minimize disruptions to motorists and neighboring residents and businesses.

PennDOT's program consists of three independent projects. The Phase 1 Resurfacing project, which was completed in 2005, covered I-476 between I-95 and Lawrence Road, which is just south of Route 3/Exit 9 (West Chester Pike) interchange, and I-95 in the area of the I-476 interchange. Construction began in June 2005 and was finished in November 2005.

The Phase 2 Resurfacing project covers I-476 between Lawrence Road and I-76/Exit 16 (Schuylkill Expressway) and I-76 in the area of the I-476 interchange. This work will start in spring 2006 and roadwork will finish in late 2006. In addition to removing the existing pavement and resurfacing I-476, PennDOT will update roadway features such as guide-rail, signing, and lane markings.

Phase 3 Reconstruction involves much more extensive reconstruction of I-476 from I-76 (Schuylkill Expressway) to the Pennsylvania Turnpike (I-276). This section of I-476 was built in the 1970s and is one of the older sections of the 21.5 mile-long highway. Since I-476 is an interstate in a densely populated suburban area, maintaining traffic on all six lanes is a high priority with this project. This reconstruction project is expected to begin in 2008 and take at least 2 years to complete.
