Permanent Speed Humps Being Installed on Grandview Avenue

PITTSBURGH, PA (June 27, 2020) The City of Pittsburgh Department of Mobility and Infrastructure (DOMI) is pleased to announce the installation of permanent asphalt speed humps on Grandview Avenue in Pittsburgh’s Mount Washington neighborhood.

The purpose of the project is to discourage motorists from speeding and to enhance pedestrian safety. Speed and volume data found that 61 percent of motorists traveled over the posted speed limit of 25 miles per hour. Temporary rubber speed humps were installed in fall of 2019 and monitored for three months. The temporary speed humps were removed in January 2020. Data collected during the pilot period found that motorists traveling over the speed limit was reduced to 32 percent.

Work is tentatively expected to begin on Monday, June 29, 2020, and is expected to last one to two days, weather permitting. Hours of construction will be Monday through Friday, 7:00 a.m. to 5:00 p.m. Alternating through traffic will be maintained, at a minimum, and temporary no parking signage may be posted.

We understand this may be a short-term inconvenience, and we hope to work together with residents in a professional and amicable manner for the long-term improvement of the neighborhood.
