The $450 million I-95/I-695 Interchange is part of the Maryland Transportation Authority's (MdTA) I-95 Express Toll Lane Mega project.  This complex interchange, designed by JMT, will relieve severe congestion in the I-95 corridor north of Baltimore by providing additional mainline capacity through additional general purpose lanes and by implementing Maryland’s first application of Express Toll Lanes. In addition, the existing left lane exits and entrances, which often confounded drivers' expectations, will be replaced.

JMT is currently providing final design services for the second of two construction contracts.  Contract #1, which is now under construction, is a $208 million project for which JMT fast-tracked the final design in only ten months. Design elements for this contract included 11 lane-miles of I-95, 12 lane-miles of I-695, 1 lane-mile of local roads and 16 lane-miles of ramps. JMT prepared structural design for 22 bridges, including 7 long flyover bridges, 38 retaining walls, 7 noise barriers and 5 culverts. The often time-consuming process of right-of-way acquisition was expedited by making JMT responsible for right-of-way acquisition and relocation assistance for nearly 100 properties.  The project must be constructed while maintaining interstate and commuter traffic, requiring JMT to develop a comprehensive phasing sequence.

Tom Warne, a former president of the American Association of State Highway and Transportation Officials and former Utah transportation chief, was quoted in a recent Baltimore Sun article about the project as saying that it “…rivals the complexity of some of the larger interchanges in Southern California including one in Orange County known as ‘Orange Crush’....This is going to put [Maryland] way at the top of complicated interchanges.”

This project is an example of the complete capabilities of JMT and the unique approaches that JMT takes to solve complex transportation problems which will “Engineer a Brighter Future” for the millions of motorists who use this facility.
