ASTORIA — A plan to turn an unused lot under the Triborough Bridge into a play space for adults, with Ping-Pong tables and volleyball courts, will kick off this fall after being delayed for two years, officials said.

Triborough Bridge Playground A, located at Hoyt Avenue North between 21st Street and Astoria Park, is expected to open in the spring of 2017 following a $825,000 redesign geared toward grown-ups, according to the Parks Department.

The space — currently a fenced off lot — will feature all-weather Ping-Pong tables, two volleyball courts and exercise equipment.

New pavement, a drain system, fences and benches will also be installed as part of the revamp, a spokeswoman said.

Plans to renovate the parkland were announced in 2013 and were initially expected to wrap up last year, but the work was delayed because crews working on the Triborough Bridge were using the lot as a staging area, according to the Parks Department.

The work is one of two major overhauls planned for the series of park spaces under the bridge.

Half of the space at Triborough Bridge Playground C — located at Hoyt Avenue North between 23rd and 24th streets and currently home to two basketball courts — is being turned into a $1 million dog run.
