About the Project

Start Date: Spring 2023
Estimated Completion Date: Spring 2027
Original Construction Cost: $148M

The purpose of the project is to correct the vertical geometry of I-95, to replace the I-95 Bridge over Route 161, and to construct new on and off ramps at Exit 74. The new on and off ramps will be completely realigned to offer easier transitions on and off the highway. These changes will bring a significant safety improvement to the area.

Due to the existing conditions, this area of I-95 has a posted speed limit of only 50 MPH. The on and off ramps at Exit 74 on I-95 lack the proper acceleration and deceleration lanes that merge on and off I-95. The existing ramps also have very tight turns. Additionally, motorists driving on Route 161 southbound are required to make a near-hairpin left turn to access the I-95 northbound on-ramp. This improvement will include a dedicated right hand turn exit lane to enter I-95 northbound.

The work on I-95 mainline is 7,032 feet long (1.33 miles), Route 161 work is 3,114 feet long (0.59 miles), and work on Frontage Road is one-quarter mile long. There will be six stages of construction.

Project Scope

Interstate 95

Improve the vertical geometry and increase design speeds throughout the project.
Add 12-foot shoulders (left/right) in both directions.
Add 6-foot raised median.
Add auxiliary lanes between interchanges 74 & 75.
Extend and rebuild on-off ramps to increase acceleration and deceleration lanes.

Bridge 00250

Replace and widen the bridge.
Improved vertical/horizontal distances and clearances which will allow for turning lane improvements on I-95 and additional capacity of Route 161.

Route 161 Improvements

Reconstruct and widen Route 161.
To accommodate a roadway cross-section of four 11-foot travel lanes & 11-foot auxiliary turn lanes.
5-foot shoulders.
4-foot utility buffer.
5-foot concrete sidewalk.
Commuter lot relocation & improvements.
