Kleinfelder provided a resident inspector and inspection staff to oversee the construction phase of this important widening and safety improvements project along the I-95 corridor in Portland, Maine. These improvements will create a safer, smoother, more efficient shortcut around Portland for motorists.

Addressing Congestion and Aging Infrastructure

The I-95 corridor is one of only three interstate highway systems in Maine. Seeing an increase in traffic and congestion in and around the area of Portland, Maine, the Maine Turnpike Authority (MTA) chose to add new lanes and safety improvements for motorists. The stretch of interstate around Portland and South Portland was constructed more than 60 years prior.

New Travel Lanes and Safety Improvements

MTA’s plan of action included the creation of new northbound and southbound travel lanes from mile marker 43 to mile marker 49 on I-95. Additionally, the grass median was reconstructed to a paved median around Portland and South Portland. An overhead sign structure located in Scarborough was also disassembled and removed. Other improvements included a closed drainage system and drainage improvements, highway lighting, paving, and safety improvements.

To assist in these efforts, Kleinfelder provided a resident inspector and inspection staff to oversee and administer the construction phase portion of this project. Kleinfelder’s team also worked closely with the materials and testing services sub-contractor to verify testing met requirements for the project.

Project Results

Kleinfelder’s resident inspector provided significant oversight of all aspects of the construction phase, which led to client cost savings, increased quality and benefits of construction, expedited contractor schedules, and aided in reducing the risk of contractor claims. Estimated completion of this project is September 2023.
