Skanska-Corman-McLean JV to start $463M Maryland bridge

Dive Brief:

  • The Maryland Transportation Authority (MDTA) has chosen the joint undertaking staff of Skanska, Corman Kokosing Development and McLean Contracting to design and style and develop a new $463 million bridge around the Potomac River connecting southern Maryland and northeastern Virginia. AECOM is the project’s lead designer.
  • Development will start out up coming month on the 1.9 mile-lengthy, 4-lane bridge around U.S. Route 301 that will exchange the Governor Harry W. Pleasant Memorial/Senator Thomas “Mac” Middleton Bridge, which is made use of by about 18,000 autos every day. The twelve-foot-extensive lanes with 2-foot shoulders will double capability and enhance basic safety, maximizing crisis response and servicing/inspection routines, in accordance to MDTA.
  • The new bridge, which will be constructed up coming to the current one, will be full by the end of 2022, after which crews will demolish the old bridge by December 2024, in accordance to Wade Watson, project director and vice president of functions for Skanska Usa Civil. The demolished bridge will be made use of as an artificial reef, a method Skanska has made use of on prior bridge tasks.

Dive Perception:

Maryland Gov. Larry Hogan has lengthy been fully commited to building a new, broader and safer bridge to exchange the two-lane Pleasant/Middleton span, which opened in December 1940 and connects Charles County, Maryland, to King George County, Virginia. According to Wade, the new concrete and metal bridge will have a a hundred-yr services lifetime. The bridge also will include things like a number of basic safety enhancements for bicyclists, together with bicycle-friendly roadway joints and clever transportation devices equipment such as lights and signage.

The bridge challenge is one of Maryland’s greatest transportation initiatives. Virginia will contribute $13 million to the challenge.

The design and style-develop approach makes perception for a challenge of this sizing, Wade instructed Development Dive.

“A single of the primary positive aspects it delivers is massive time discounts,” he claimed. “On a standard design and style-bid-develop the proprietor would have to go out and price the challenge and negotiate a contract right after it is really been developed. With design and style-develop you can be creating at the same time you’re building.”

When the new bridge and roadway building are full, the current bridge will be demolished and made use of to make artificial reefs in the Chesapeake Bay watershed. These manmade buildings mimic some of the attributes of a natural reef, according to the National Oceanic and Atmospheric Administration, and are generally composed of building elements like rocks, cinder blocks, concrete, wood and tires. 

The reef approach has been made use of by Skanska for several years, Watson claimed, most lately on the Pensacola Bay Bridge project in Florida.
