Maryland Lt. Governor Anthony Brown, Harford County Executive David Craig, and Maryland State Highway Administrator Melinda Peters celebrated the completion of the newly-improved US 40 (Pulaski Highway) and MD 715 interchange in Aberdeen on September 9, 2013, marking the culmination of a nearly three year, $17.8 million project.

The Maryland State Highway Administration (MSHA) chose the Design/Build team of Johnson, Mirmiran & Thompson (JMT) and American Infrastructure to spearhead the project in 2010.
The new interchange – a total project length of 2.4 miles – helps alleviate traffic traveling east and west past Aberdeen Proving Ground (APG), which has grown considerably in the past several years due to the US Department of Defense’s Base Realignment and Closure (BRAC) initiative.

“These improvements are going to make it easier for all residents to be able to spend less time behind the wheel in the car, behind another car, and more time either with their families or on the job being productive,” Brown declared during Monday’s ribbon cutting ceremony, according to The Aegis newspaper.

Craig, Peters, Aberdeen Mayor Michael Bennett and Maj. Gen. Robert Ferrell, APG’s ranking general, echoed Brown’s praise. Bennett acknowledged that the city is already beginning to see the positive effects of the improvements.

As part of the first phase of the project, MD 715 was widened in both directions between the Amtrak Bridge and entrance to APG. In Phase 2, the bridge on MD 715 over US 40 was also widened.

JMT designed the improvements to the interchange, connecting ramps and adjoining roadways. Other services that contributed to the project’s success included stream relocation designs, drainage design, traffic and lighting, landscaping, utility relocation design and coordination, and obtaining permits from the Maryland Department of the Environment for construction.
