Shady Avenue Traffic Calming Speed Hump Installation

PITTSBURGH, PA (August 27, 2021) The Department of Mobility and Infrastructure is pleased to announce the next phase of traffic calming measures on Shady Avenue from Pittock Street to Nicholson Street, near Taylor Allderdice High School. Data collected in 2020 indicated that 75% of vehicles traveling on Shady Avenue in this area exceed the posted speed limit of 25 mph, with an 85th percentile speed of 33 mph. The rate of speeding, especially on a school corridor where many students walk, indicated a strong need for a traffic calming intervention.

This portion of the project will include the construction of one speed hump on Shady Avenue. Permanent signage and pavement markings will be installed to alert motorists of approaching speed humps. Speed humps are midblock traffic calming devices that raise the entire wheelbase of a vehicle to reduce its speed.

Work is tentatively expected to take place on Saturday August 28, 2021, and is expected to last one day, weather permitting. Hours of construction will be 7:00 a.m. to 5:00 p.m. One lane of traffic on Shady Avenue will be closed to traffic, with flaggers stationed at each intersection in order to allow local traffic access to and from their residences. Temporary no parking signage will be posted at each speed hump location.

Thank you for your cooperation during this time and we hope there will be only minor inconveniences.
