Mt. Washington's Grandview Avenue Getting Permanent Speed Humps

PITTSBURGH, PA — City workers on Monday will begin installing permanent asphalt speed humps on Grandview Avenue in Mount Washington.

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.
