Traffic through the inbound and outbound Squirrel Hill Tunnels will be restricted tonight into Saturday morning this week but both tunnels will be fully open the rest of Saturday and all of Sunday.
According to PennDOT, inbound traffic will have only one lane available from 9 p.m. today through 10 a.m. Saturday.
Traffic outbound will be limited to one lane beginning two hours after the end of the Pirates and Penguins games. Those restrictions end at 10 a.m. Saturday.
The restrictions are part of a $49.5 million project set to improve electrical systems, lighting, ventilation, structural repairs, tile repairs, and install a water line.
