About the Project
This design-build project will realign the entrance and exit ramps at the I-95 interchange at Temple Avenue and replace the signalized intersection with a roundabout. The roundabout will be relocated west of the current intersection and will include two lanes for traffic and a continuous bypass lane on the westbound approach. The I-95 ramps will be extended and improved to provide better sight distance, vehicle capacity and transition from interstate speeds to the Temple Avenue roundabout. This plan will require removing the Temple Avenue bridges to construct the roundabout.
Major project milestone dates:
- Notice to Proceed – February 24, 2015
- Right-of-way Acquisition Commences – August 2015
- Final Design Plans – December 2015
- Utility Relocations – February 2016 to April 2016
- Project Construction – March 2016 to November 2017
The purpose and need of this project is to improve traffic flow through the I-95/Temple Avenue Interchange, to eliminate prolonged periods of delay and to decrease the accident rate within the project limits. The project will address current deficiencies in capacity, geometry and safety.
Why a roundabout?
The roundabout design was chosen as the most efficient design for this congested intersection to provide improved safety and traffic flow. A roundabout reduces traffic and wait times by allowing traffic to continually move at a low rate of speed versus coming to a complete stop at signals. This will be especially important during peak traffic hours.
The project will realign the southbound and northbound I-95 off ramps to eliminate the existing yield condition. The signalized intersection at the interchange will be removed and replaced with a roundabout.
The proposed roundabout includes two lanes of circulation and a continuous bypass lane on the west bound approach. Both the northbound and southbound I-95 off-ramps are extended and improved to provide motorists greater distance and improved curvature for transition from the high speed mainline to the arterial. The northbound I-95 off-ramp is improved to provide for a free-flow movement and eliminate the existing yield controlled condition.
How will traffic move through this area?
