Skanska has been awarded a $60.2 million contract by the Metropolitan Transportation Authority (MTA) to work on East Side Access, the MTA’s largest capital project and one of the largest active transportation infrastructure projects in the nation.
East Side Access marks the first expansion of Long Island Rail Road (LIRR) in over 100 years.
Along with the Third Track, the transformational project will deliver faster commutes, fewer delays, greater reliability, and more options for MTA customers.
When complete, East Side Access will enable direct access to a brand-new concourse and terminal on the east side of Manhattan for riders on all eleven branches of the
LIRR, easing overcrowding in and around Penn Station and connecting the region like never before.
“Skanska is honored to be selected to complete the final major civil contract for the East Side Access project,” said Mike Viggiano, Executive Vice President, Skanska USA Civil. “Strengthening our regional transportation infrastructure is a critical issue that will benefit all New Yorkers. From the Second Avenue Subway and LIRR Double Track to the redevelopment of LaGuardia Airport, Skanska is proud to play a leading role in delivering many of the largest transportation projects in the region.”
Under the contract, Skanska will utilize cut-and-cover and open cut methods to construct a new 800-foot tunnel structure at the Harold Interlocking, the busiest passenger interlocking in North America with over 800 train movements a day.
Skanska will excavate a total of 20,000 cubic yards of soil to make room for the new structure. The contract also contains two additional options to install new tracks and switches.
Construction is set to begin in Spring of 2019 and be completed by mid-2021. This will allow the LIRR to begin service to Grand Central Terminal by the end of 2022.
To complete the work, Skanska will also extract and remove a tunnel boring machine cutter head that was left in place following the completion of work by a prior contractor.
This will allow the project team to connect the tunnel to the rest of the LIRR network by way of the new, 800-foot structure Skanska will be constructing. The project will also require Skanska to install temporary supports for the nearby 39th Street Bridge as the team conducts excavation and new construction below the structure.
