  • The Maryland Transportation Authority (MDTA) has selected the joint undertaking crew of Skanska, Corman Kokosing Development and McLean Contracting to style and design and make a new $463 million bridge in excess of the Potomac River connecting southern Maryland and northeastern Virginia. AECOM is the project’s guide designer.
  • Development will start off following month on the 1.nine mile-prolonged, four-lane bridge in excess of U.S. Route 301 that will swap the Governor Harry W. Wonderful Memorial/Senator Thomas “Mac” Middleton Bridge, which is employed by about 18,000 vehicles day-to-day. The 12-foot-large lanes with 2-foot shoulders will double capability and strengthen basic safety, boosting unexpected emergency response and upkeep/inspection pursuits, according to MDTA.
  • The new bridge, which will be constructed following to the current a single, will be full by the conclude of 2022, after which crews will demolish the previous bridge by December 2024, according to Wade Watson, project director and vice president of functions for Skanska United states Civil. The demolished bridge will be employed as an artificial reef, a approach Skanska has employed on prior bridge initiatives.

Dive Perception:

Maryland Gov. Larry Hogan has prolonged been committed to making a new, broader and safer bridge to swap the two-lane Wonderful/Middleton span, which opened in December 1940 and connects Charles County, Maryland, to King George County, Virginia. According to Wade, the new concrete and steel bridge will have a 100-year service lifetime. The bridge also will include things like numerous basic safety enhancements for bicyclists, which includes bicycle-pleasant roadway joints and smart transportation methods applications such as lights and signage.

The bridge job is a single of Maryland’s major transportation initiatives. Virginia will contribute $13 million to the job.

The style and design-make tactic tends to make feeling for a job of this dimension, Wade instructed Development Dive.

“1 of the most important gains it provides is big time discounts,” he claimed. “On a common style and design-bid-make the proprietor would have to go out and cost the job and negotiate a deal after it’s been built. With style and design-make you can be creating at the very same time you are making.”

After the new bridge and roadway construction are full, the current bridge will be demolished and employed to build artificial reefs in the Chesapeake Bay watershed. These artifical constructions mimic some of the qualities of a natural reef, according to the National Oceanic and Atmospheric Administration, and are frequently composed of construction materials like rocks, cinder blocks, concrete, wood and tires. 

The reef tactic has been employed by Skanska for several years, Watson claimed, most just lately on the Pensacola Bay Bridge project in Florida.
