Allegheny River lock chamber closure to cause delays

The U.S. Army Corps of Engineers Pittsburgh District is alerting mariners of scheduled closures at Allegheny River Lock and Dam 2 on the Allegheny River from August 5 to November 1 due to repairs to the facility’s land wall.

Maintenance will require intermittent closures of the facility’s lock chamber during the following times:

August 5 at 7 a.m. to August 26 at 7 a.m. – full chamber closure
August 26 at 7 a.m. to September 9 at 5 a.m. – chamber open with 35-foot width restriction

September 9 at 7 a.m. to September 27 at 6 p.m. – full chamber closure
September 27 at 6 p.m. to September 30 at 5 a.m. – chamber open with 35-foot width restriction

September 30 at 5 a.m. to October 18 at 10 a.m. – full chamber closure
October 18 at 10 a.m. to October 31 at 10 a.m. – chamber open with 35-foot width restriction

October 31 at 10 a.m. to November 1 at 2 a.m. – full chamber closure
November 1 at 2 a.m. – chamber fully open

Additionally, during the width-restriction periods, commercial vessels will be given priority over recreational vessels when locking through. Recreational boaters should plan accordingly.

High water conditions may delay the start and progress of some work. The district will continue to provide updates regarding how a delay will affect the timeline.

The scheduled closures of the lock chamber are necessary to address lock chamber wall repairs needed to reduce the risk of unscheduled closures and maintain the reliability of the navigation facility.

Please see the navigation notice concerning restrictions and changes in locking through procedures for the lock.
