Army Corp of Engineers officials announced Monday a project that will a bridge over Keystone Dam beginning in October.
The Tulsa District U.S. Army Corps of Engineers stated the Highway 151 bridge over Keystone Dam will be closed beginning Oct. 28. The project will last for 13 months.
According to Tulsa's Channel 8's community newspaper partner, The Mannford Eagle, speed of construction factored into every element of the innovative and atypical bridge. The design uses precast concrete components to increase the speed of construction.
Elements will be precast at fabrication plant facilities and shipped to the worksite, reducing the time on site it typically takes to form and cure elements. Elements can also be constructed simultaneously, reducing lag time waiting for one element to be completed before starting the next.
An engineering analysis found that the bridge, built in 1964, is at the end of its useful life. Not replacing the bridge could risk an unplanned extended closure that could last longer than this planned project.
Areas around Keystone Dam will experience construction traffic and some recreation access points may be impacted. Most day use and camping facilities will remain available to the public.
