PITTSBURGH – The U.S. Army Corps of Engineers announced that Allegheny River Lock and Dam 2 will return to normal operations Nov. 14 after a $6,619,369 rehabilitation.
The project provides a value of more than $160 million in commercial and $250,000 recreational economic benefits to the region and the nation.
By repairing and improving the concrete rubbing surface on the land wall of the chamber, the Corps is providing a safer locking experience for both recreation and commercial navigation users.
“Improving infrastructure and safety are major focuses for the district,” said Col. Andrew “Coby” Short, commander, Pittsburgh District. “We are thrilled that we are creating a long term safe solution for the thousands of vessels who transit this facility every year.”
The construction contract was awarded in September 2018 to C.J. Mahan Construction Company, LLC.
Construction activities started in early 2019 with preparation work to install new concrete on the face of the land wall. The project required several closures throughout the summer, with the final closure ending Nov. 14.
Repairs involved removing deteriorated concrete and installing a new land wall rubbing surface constructed with pre-cast concrete panels.
BACKGROUND: Allegheny River Lock and Dam 2 was constructed from 1932 to 1934 and put into operation in 1934. The facility is located at river mile 6.7, and approximately the same distance from the confluence of where the Monongahela River and Allegheny Rivers meet to form the Ohio River.
