Liberty Bridge work to begin
Deck replacement work on the Liberty Bridge in Pittsburgh will begin Monday, weather permitting.
“This launches the major work to upgrade the Liberty Bridge we have been planning for many years,” said District Executive Dan Cessna. “We appreciate everyone’s patience during this multiple phase effort.”
Beginning at 5 a.m. Monday, deck replacement work will begin on the bridge. The deck will be replaced one lane at a time through four separate work phases over the course of approximately 160 consecutive days. The first phase begins with the far right inbound lane closure and includes the closure of the inbound bridge ramp to the Boulevard of the Allies. This lane closure will continue for approximately 45 days.
During each phase of construction, the traffic configuration will be changed three times each weekday. Three lanes of traffic will be maintained during peak travel times and two lanes will be maintained overnight. ·
Two inbound (northbound) lanes and one outbound (southbound) lane will be maintained from 5 a.m. to 2 p.m. each weekday.
Two outbound (southbound) lanes and one inbound (northbound) lane will be maintained from 2 p.m. to 8 p.m. each weekday. A single lane of traffic will be maintained in each direction from 8 p.m. to 5 a.m. each weeknight.
To allow each configuration to occur, a short traffic stoppage of 15 minutes or less will be implemented for each traffic switch. Crews will shift channelizers, cover signs and change message boards.
Ramp reconstruction work will occur this year, beginning with the inbound bridge ramp to the Boulevard of the Allies. The ramp will close for approximately 52 days and traffic will be detoured.
