Project Overview

​Project to improve the Interstate 80 Exit 310 (PA 611/Delaware Water Gap) interchange in Monroe County.
The project entails replacing the Exit 310 on-ramp bridge to I-80 east in Smithfield Township, and the Exit 310 off-ramp from I-80 west in Delaware Water Gap Borough. Both ramps traverse I-80.
Also, the project includes replacing the existing signalized intersection where Broad Street, River Road, Foxtown Hill Road and the Exit 310 ramps meet in Smithfield Township with a roundabout. 
The main characteristics of a modern roundabout include: generally circular shape; yield signs at the entrances; geometry that forces slower speeds; and counterclockwise circulation of traffic. Also, unlike traffic signals, roundabouts do not depend on electricity to function, so they are not susceptible to power outages. More information on roundabouts can be found at

Detour Information

New traffic patterns are in effect at the intersection where Broad Street, River Road, Foxtown Hill Road and the Interstate 80 Exit 310 ramps meet in Smithfield Township.

The modern roundabout at the intersection opened on November 20, and all detours in the area have been removed. However, work in the center of the roundabout to complete the truck apron and work on several splitter islands continues so motorists should remain alert for lane restrictions in the area.

All schedules are weather permitting, and updates will be provided to the public in advance of any traffic pattern changes.
