Tunnel on I-895, was recently completed by Swank Construction Company from New Kensington, PA. A major focus of the job was the restoration of the driving surface slab within the Harbor Tunnel. Both driving lanes through each tube of the tunnel were rehabbed. This was a two-year project that began in 2019 and concluded in 2020. The total amount of improvements was just under 50,000 square yards.
The Northbound lanes were closed in early April 2019, and traffic was diverted into the Southbound tube during the temporary closure, with single head to head traffic in each direction. A 60-day closure was permitted for the work.
Then in April 2020, traffic was closed in the Southbound tube and diverted to the Northbound lanes in similar fashion, with head to head traffic and another 60-day allowable closure period.
The removal depth of the surface was 2” inside the tunnel by a combination of milling and hydrodemolition. The reinforced approach pavement leading into the tunnel included up to 6” of removal, plus a new mat of stainless steel rebar was added. Latex Modified Concrete (LMC) was used to resurface the 9,219 feet x 22 feet of travel lanes in each direction. HTNE Hydrodemolition Services, LLC, performed the hydrodemolition work.
The Northeast Division of Modified Concrete Suppliers, LLC, from New Kensington, PA, produced the LMC. Modified produced over 4,400 cubic yards of High Performance Latex Modified Concrete for the two phases of work. This included 2,155 cubic yards of LMC in the Northbound tube, and 2,283 cubic yards of LMC for the Southbound tube.
