The I-476/Blue Route Improvement Project

Welcome to your website for the I-476/Blue Route Improvement Project.

The Pennsylvania Department of Transportation has substantially completed the roadway portion of the final phase of its four-phase program to reconstruct and improve Interstate 476 in Montgomery and Delaware counties. Though original traffic patterns - three lanes in each direction - have been re-established, motorists are reminded that the Exit 16 through Exit 20 work zone will remain active well into 2012 and that off-peak lane closures are possible in either direction as crews complete construction items on both the top side and under side of the interstate.

Construction on the two multi-million dollar projects to rebuild the northern segment of the expressway -- from Interstate 76 (Schuylkill Expressway) to the Turnpike's Mid-County Interchange -- got underway in early 2009 with the start of the $47.4 million re-decking of the northbound and southbound bridges over the Schuylkill River (Phase 3).  Work on the bridges finished on schedule in November 2010.

In early 2010, PennDOT, utilizing federal and state funds, began rebuilding 3.5 miles of I-476 (Phase 4) between Exit 20 and Exit 16. Reconstruction of the southbound side of I-476 finished in December 2010, and crews immediately began preparing the work zone traffic pattern for reconstruction of the northbound lanes in 2011. Major construction on the northbound side finished in late-October, 2011.

We will continue to use this website to keep you informed of the work that is taking place and the potential impacts that it may have on your travel as we complete the rebuilding of this busy interstate in 2012. You may subscribe to have project news, updates and emergency communications sent to your e-mail, cell phone or PDA, or follow us on Twitter to receive short text alerts on regional travel conditions as part of PennDOT's 511 system for southeast Pennsylvania.

What are the huge mounds that have been built at the I-476/I-76 Interchange and along the northbound lanes near Ridge Pike?  Go here for more.
