To move the project ahead with as little traffic interruption as possible and provide a safe environment for motorists and construction workers, a 200-ton, 200-feet-long Acrow modular bridge was ordered and installed in March 2017. The temporary bridge was constructed on-site and assembled in the median space between the existing bridges. It was initially configured to carry eastbound traffic while the deck on the eastbound route was renovated. Upon completion of that phase of the project, westbound traffic was routed over the temporary structure in order to allow for renovation of the westbound deck.

Detour solutions such as this are being increasingly used by state DOTs. Work zone fatalities continue to be an increasing problem and the use of bypass bridging is one method to ensure a safe worksite. Providing a route that separates vehicles from a construction zone is far safer for both motorists and workers in the area. Additionally, in order to minimize traffic delay costs, keeping traffic moving at speed is critical, especially on a busy interstate highway like I-10. Other re-routing options such as a frontage road bypass or a cross-over splitting the road with head-on traffic would slow traffic greatly.

It is expected the Acrow structure will be in place until completion of the project in late fall 2017.

“Acrow modular detour bridges are a logical choice for state DOTs and contractors who need to stay on or ahead of schedule and, at the same time, assure motorist and worker safety,” said Bill Killeen, President and CEO of Acrow Bridge. “Acrow modular detour bridges, available for rent or purchase, are cost-effective and provide safe and reliable passage for motorists and enhanced safety in the construction zone.”
