With average daily traffic volumes of 140,000 vehicles, this section of I-95 experiences high congestion and high crash volumes. A key goal of this project is to implement congestion reduction improvements as part of the long-term congestion reduction strategy for I-95 in southwest Connecticut. This work includes a new I-95 southbound auxiliary lane between Exit 7 and Exit 6. GM2 performed traffic operational analysis and simulations to evaluate the existing and proposed freeway merge, diverge, weaving, and interchange ramp terminal operations using HCS, SYNCHRO and SIMTRAFFIC software.
The project also consists of comprehensive structural pavement rehabilitation to extend the service life and restore functionality of I-95. The underlying concrete pavement is 60 years old is reaching its serviceable life. Pavement joint rehabilitation and replacement of concrete slabs are required. The project includes improvements to two interchanges, installation of noise walls, installation of an Incident Management System and upgrades to the existing drainage and lighting.
