Specifications include, but are not limited to: GIMLET HOLLOW O/P, located in Cabell County. The twin structures carry Interstate 64 over Cook School Road, East Road, and West Road and is located 0.47 mile west of United States Route (US) 52. Eastbound and Westbound bridges consist of girder floor beam stringer system with eight (8) spans, having an overall length of 905 feet 6 inches and a deck width out-to-out of 35 feet 3 inches. The professional engineering services for this replacement project shall include the design of construction plans and right-of-way plans, surveying, geotechnical services, and traffic engineering services with special consideration to Design Directive 681 – Work Zone Safety and Mobility. During Phase I of Maintenance of Traffic (MOT) a portion of the permanent bridge will be constructed in the median to maintain two lanes of westbound traffic while the existing westbound bridge is demolished, and the permanent is constructed. During Phase II of MOT the westbound traffic from the median will be transferred to the newly constructed westbound bridge and existing eastbound traffic moved to median portion of the bridge while eastbound bridge is demolished, and the permanent bridge is constructed. NEPA clearance will be handled by Technical Support Division. The superstructure for both eastbound and westbound bridge is fracture critical. There is a tear in the beam in the westbound bridge. The acceleration and deacceleration lanes at Exit 6 may be substandard and may possibly require upgrading with this project. There are utilities under the bridge and the bridge also has bats.
