Liberty Bridge Reopens to Traffic
 
Pittsburgh, PA PennDOT District 11 is announcing the Liberty Bridge (Route 3069) in the City of Pittsburgh, Allegheny County, has reopened to traffic today, Monday, September 26.
 
“We are very pleased with the team effort over the last 24 days that has allowed us to repair the Liberty Bridge and ensure it’s safety,” said H. Daniel Cessna, P.E., District Executive for Engineering District 11-0.  “I want to thank motorists for their patience as these critical repairs were made to the bridge.”
 
Temporary repairs to realign the damaged lower chord have been completed.  The jacking process, in conjunction with localized heating, has straightened the chord and redistributed the load on the bridge.  The bridge will temporarily have a 9 ton weight limit as crews continue to add steel to strengthen one truss chord.  Once completed, the bridge will be placed under the pre-closing weight limit of 30 tons.  A permanent repair will be designed and installed.
 
When reopened, crews will continue with bridge deck replacement work.  Work on the far right southbound (outbound) lane will continue.  As a reminder, the traffic configuration on the bridge will be changed three times each weekday (see attached graphic). Three lanes of traffic will be maintained during peak travel times and two lanes will be maintained overnight.  The traffic patterns will occur according to the following schedule:
 
·        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.
·        Work may occur on Saturdays and Sundays.  Additional information will be provided if work occurs.
 
The Liberty Bridge was closed to traffic Friday, September 2 due to a fire that damaged approximately 30 feet of the lower compression chord of the deck truss.

30 Ton Weight Limit Restored on Liberty Bridge
 
Pittsburgh, PA PennDOT District 11 is announcing a 30 ton weight limit has been restored on the Liberty Bridge (Route 3069) in the City of Pittsburgh, Allegheny County.
 
A temporary nine ton weight limit was implemented on the Liberty Bridge when it reopened to traffic on Monday, September 26, while crews worked to add steel to strengthen a truss chord.  The repair was completed this morning and the pre-closure 30 ton weight limit has been restored on the bridge.  Once the rehabilitation project is complete in 2018, it is anticipated that the bridge will have a 40 ton weight limit.
 
The bridge now will be able to accommodate heavier vehicles such as fire trucks, buses and delivery trucks.  (See attached graphic)  However, the average loaded dump truck (approximately 36 tons) and tractor trailer (approximately 40 tons) will still be prohibited and are subject to enforcement.  Weigh teams from the Pennsylvania State Police and other law enforcement agencies will continue to conduct checkpoints and roving patrols.  Vehicles weighing more than the posted weight limit will need to use the posted detour routes.
