The West Virginia Department of Highways bid a three span steel girder bridge for the I-64 overpass over the local road. The contractor Ahern & Associates presented to the WVDOH a value engineering proposal to redesign the bridge at grade to be a buried bridge using a high profile shaped concrete arch. The value engineering proposal provided a savings of approximately 20% when compared to the three span steel girder bridge bid.

A BEBO® Concrete Arch Structure C54 was chosen because it provided for a quick installation which was essential in order to maintain use of the highway above, the local road below, and have a minimal effect on the surrounding community.

The 54’ span, 24-ft. – 4-in. rise structure runs 158-ft. long and has cast-in-place concrete footings, precast arches and MSE headwalls and wingwalls. Fill height over the top of the arch was approximately 20 -ft. The shape of the arch provided for an efficient design for the high cover requirement.

The roadway was only closed from 8:00 p.m. to 6:00 a.m. daily during construction, keeping the local road closure time to a minimum. The original maintenance of traffic scheduled for two construction seasons was reduced to one construction season. This provided a huge safety bonus to the traveling public and to the contractor. With lower material costs and fast installation times, BEBO proved to be an economical and successful vehicular overpass solution for the West Virginia Department of Highways.
