Rehabilitation of Park Avenue Tunnel
Contract No. HBM551
PIN No. 84108MBBR345
The New York City Department of Transportation Division of Bridges maintains the Park Avenue Tunnel, and the project to rehabilitate and repair this 100+ year old structure began in February 2017. This tunnel runs from East 33rd Street to East 40th Street beneath the Park Avenue malls. The Park Avenue Tunnel Rehabilitation will be done in phases. The work involves structural, electrical, mechanical and fire protection improvements, and will also include safety improvements at intersections and beautification of surrounding areas. For the outside renovations and improvements, the DOT is planning to use construction materials consistent with the character of the neighborhood and will restore any areas that are disturbed. The project is expected to continue through 2019 at a cost of $24 million.
The Work Zone Traffic Control area was established, and advisory signs have been posted at the south portal alerting drivers to the road narrowing ahead as the travel lane inside the tunnel has been reduced to 9 feet 6 inches. For increased safety, speed limits have also been reduced in the tunnel from 35 mph to 15 mph.
Work hours / Tunnel closure hours:
Weeknights: 9pm to 6am
Weekends: 9pm Friday night to 6am Monday
- The installation of a new sub-surface drainage system was completed.
- The tunnel roadway subbase and base concrete on the east side of the tunnel were installed.
- The asbestos abatement inside the tunnel was finished.
What's coming next
- Lead paint will be abated from newly exposed bricks on the tunnel roof.
- The 34th Street Mall will be refurbished with wider walkways and safety improvements. Parapet walls will be repaired and restored.
The NYC DOT is taking every measure to ensure that inconveniences during construction are kept to a minimum:
- Environmental monitoring services are in place and noise decibel levels are being monitored with sound level meters so that they do not exceed the levels established by NYC DEP.
- Noise reducing blankets are utilized during night time construction at the entrance and exit to the tunnel. These barrier blankets are designed to provide noise control while construction work inside the tunnel is in progress.
- Green mesh privacy netting has been installed over the fencing at the construction storage area on East 40th Street. This privacy tarp keeps dust particles from spilling into the surrounding area and hides the work materials.
- The construction yard was re-located to the southbound side of Park Avenue between East 40th and East 41st Street.
