A community’s aesthetic considerations, a traffic fatality caused by its flooding, concerns over road closures and an expanding project scope on a limited budget were significant factors in this Hays County project, just west of Austin.
Project’s heralded success builds opportunities
Big R Bridge worked carefully with the Texas Department of Transportation (TXDOT) and all other parties to deliver a win-win solution. In fact, Hays County and TXDOT representatives joined Big R in presenting the project at the recent Texas Association of County Engineers Conference in San Antonio, spurring positive growth between the TXDOT and other communities in Texas Hill Country.
Satisfying aesthetic, hydraulic, safety, traffic and budget concerns
Due to its close proximity to a TXDOT intersection improvement project, this bridge was added to that overall scope, creating extra budget pressures. The existing low-water crossing was simply a pair of smaller culverts under a dip in the road that flooded on a regular basis. Recently, a fatal accident occurred during a flood. The local community of Driftwood, the County and the TXDOT needed to find a cost-effective solution that would appease everyone.
Packaging a solution that works for all
Although the community had initially resisted the move to a larger structure, the aesthetics, increased flow, improved safety, quick installation and economic benefits of the Big R solution helped sway them. The project partners were happy that we could help save time and money by packaging the design and fabrication for both the plate arch bridges and the MSE headwalls.
Our own engineering team worked with the consultant to come up with a suitable solution that featured an elegant pair of Low-Profile Arches in our Bolt-A-Plate Structural Steel Plate, with naturally-colored Vist-A-Wall Precast Panel Headwalls in the Ashlar Stone texture. Custom-fabricated dark brown safety railings completed the picture.
