The Pittsburgh Port District encompasses a twelve county area which includes three major rivers in southwestern PA: the Allegheny, the Monongahela, and the Ohio. This waterway is made navigable by a system of seventeen locks and dams.

Montgomery Locks and Dam
100 Montgomery Dam Road
Monaca, PA 15061-2221


Project Description

Facility is located on the Ohio River, 32 miles downriver from Pittsburgh near Shippingport, PA. It was built from 1932-1936 and began operation in June 1936. It is comprised of a 1,379 foot gated dam, a 110 ft x 600ft land side lock, and a 56ft x 360ft river side lock which provide for a 17.5 foot vertical lift.


Transportation Importance to the System


Montgomery L/D is the third of six navigation facilities on the Ohio River operated by the Pittsburgh District. From 2000 to 2007, Montgomery Locks averaged 1,156 recreational vessels, 4,913 commercial tows, and 23.0 million tons of cargo. Cargo consists of coal, petroleum, chemicals, crude materials, manufactured goods, farm products, manufactured machinery, and other commodities. Coal is the principal commodity at Montgomery. Electric utilities move coal from mines in Pennsylvania and Ohio to power plants serving the mid-Atlantic, southeastern and midwestern regions of the United States. Steel companies move coal from West Virginia and Kentucky mines to coking facilities on the Monongahela River. Construction and supply companies use this facility to move raw materials into the region. Average annual transportation cost savings associated with this facility from 2000 to 2005 is over $197 million.

Risk of economic impacts of unscheduled lock outages

Failure to provide adequate funding to maintain this facility will have significant detrimental effects to the local and regional economy. Failure of the dam or any critical lock component in the main or auxiliary chambers, or both, will result in increased transportation costs and delays to the shipment of critical raw materials for power production, manufacturing, and other commercial activities.

Scope of work to achieve acceptable level of risk

The projected 5 year (FY 2010 through FY 2014) average cost to operate and maintain Montgomery Locks and Dams at an acceptable level of risk is $5.8M per year. Maintenance items include maintenance, repair, and/or replacement of lock operating equipment; lock gates, anchorages, and sills; lock valves; lock walls; repair or replacement of dam gates; dam operating machinery; and hydraulic systems. These costs are above and beyond the routine day to day maintenance of all system components.
