Motorists are facing lane restrictions as construction work continues on Pittsburgh's Liberty Bridge.
The Boulevard of the Allies closes for 80 days between Grant Street and the bridge beginning at 6 a.m. Monday.
Weekday lane restrictions also have resumed. Two inbound lanes and one outbound will be open from 5 a.m. to 2 p.m. and motorists will have one inbound and two outbound lanes from 2 to 7 p.m.
One lane is open in each direction from 7 p.m. to 5 a.m.
The work is part of the Transportation Department's $80 million bridge rehabilitation project.
