WORK TO ADDRESS SEEPAGE AT I-664 MONITOR-MERRIMAC MEMORIAL BRIDGE-TUNNEL COMPLETED EARLY
SUFFOLK - A project to divert water from seeping up from the ground and onto the roadway of the I-664/Monitor-Merrimac Memorial Bridge-Tunnel (MMMBT) was completed early and has proven successful in significantly reducing the problem for motorists and maintenance crews.
Drivers have long encountered wet pavement at the entrances and exits of the MMMBT because of groundwater seepage. In addition to being a nuisance for the public, the wet pavement contributed to potholes and required VDOT to treat the roadway during cold weather to keep it from freezing.
VDOT engineers designed a solution that redirects seeping water before it reaches the surface of the road and diverts it to the tunnel's existing drainage system.
Curtis Contracting began the joint work in February and finished in early May, more than a week ahead of the project's scheduled completion date. Inspectors have since found no evidence of water seepage returning to the roadway.
VDOT plans to re-pave the areas near the tunnel's openings at a later date.
