Advanced Traffic Management System Along I-495

McCourt Construction, MassBay Electric and Jacobs Engineering have partnered to design and construct a new Advanced Traffic Management System along 50 miles of Interstate 495. The scope includes 29 CCTV cameras, in addition to variable message boards, traffic counters, and a new five-mile 96-strand fiber backbone down the median of the highway. This design-build project will tie Interstate 495 into MassDOT’s existing ATMS infrastructure in Boston.

Runway 22R End Safety Improvements

McCourt was the low bidder on a project that will replace the EMAS system at the end of Runway 22R. EMAS is an arrestor bed designed to halt a plane before it can overshoot a runway. The existing system was the first of its kind installed at Logan and had reached the end of its useful life (incidentally, it was also installed by McCourt decades ago). Additional scope included tidal work installing an inclined safety area past the end of the runway. This involved replacing a swampy expanse with a thick bed consisting of 900 truckloads of specialty aggregate.

Callahan Tunnel Rehabilitation

This high-profile project features the complete closure and rehabilitation of the Callahan Tunnel under Boston Harbor. The Callahan Tunnel is one of only two tunnels to Logan Airport. As such, MassDOT devised a heavily incentivized schedule that permitted 24/7 work shifts for 72 days. McCourt reopened the tunnel four days early in March of 2014. Work continues replacing the wall panels within the tunnel. A MassDOT project page can be found here.

Massachusetts Ave Streetscape Improvements

McCourt began construction in early 2014 on a MassDOT project that includes the complete reconstruction of the intersection of Huntington and Massachusetts Avenues. It also includes the reconstruction of the Mass Ave Bridge and the historic sidewalks/streets around Symphony Hall and the Christian Science Plaza. In an exciting sidenote to this project, McCourt has already uncovered a previously unknown portal (c. 1900) to the Green Line – America’s first subway.
