The Hudson Yards Concrete Casing – Section 3 Project will enable the new tunnel to pass under Hudson Yards on its way to New York Penn Station.
The Hudson Yards Concrete Casing – Section 3 (HYCC-3) Project is building the final section of the rail right-of-way beneath Hudson Yards, which will connect the new tunnel into New York Penn Station.
The construction of the concrete casing beneath Hudson Yards has been in progress since 2013. Sections 1 and 2 were built under the block bordered by 10th and 11th Avenues and 30th and 33rd Streets and completed in 2018.
HYCC-3 is extending the concrete casing that has already been built from 11th Avenue to 30th Street, where it will connect to the new tunnel. This section of the concrete casing is approximately 500 feet long, 60 feet wide, and 60 feet high. Its structure will consist of heavily reinforced concrete ranging from 3.5 to 10 feet thick with a waterproofing membrane covering its perimeter.
