Welcome!
Traffic relief is on the way for motorists traveling to and from the bustling business parks in Chester County’s Great Valley as the Pennsylvania Turnpike begins construction of its Route 29 All-Electronic Interchange.

The new interchange, with new on- and off-ramps eastbound and westbound, will provide a clear alternative to US Route 202 and other surface roads that feed the busy Route 29 Corridor. In addition to shortening commuter travel times, the new ramps will ease congestion at Valley Forge (Exit 326) and Downingtown (Exit 312) – neighboring Turnpike Interchanges used by many Route 29-bound drivers – and provide a measure of relief for often overloaded surface roads serving the corridor.

New Exit 320 at Route 29 will be an all electronic interchange for the exclusive use by the Turnpike's E-ZPass customers.

As we build your new ramps, we’ll use this website to keep you informed about the progress of construction and any impacts this work may have on your day-to-day travel. Use the buttons on the left to obtain more information about the Route 29 All Electronic Interchange project, to sign up to receive project information by email or text message, or to enroll in the Turnpike's E-ZPass program.

Construction is now underway, so please drive safely and distraction free.
