Pittsburgh will install speed humps on Merrimac Street next month to slow traffic, the city’s Department of Mobility and Infrastructure said Thursday.
They will be installed between Grandview Avenue to Woodruff Street in an effort to slow traffic on Mt. Washington.
The city collected data in the spring that showed more than 80% of the vehicles traveling on the street were going 35 mph, which is above the posted 25 mph speed limit on the street.
Four speed humps, signage and pavement markings will be installed starting June 1, weather permitting. The work is expected to take two days and the street will be closed to non-local traffic, the city said.
Flaggers will be stationed at each intersection in order to allow local traffic access to and from their homes.
