A temporary bridge vs. detours

When disaster hits — caused by storms or other structural failures, figuring out the safest way to build new access is always a challenge, and it comes down to road closures, detours, or temporary bridges. And most of the time, a temporary bridge is the best alternative.

Which choice is the safest solution for your situation?

Road closures and detours are a necessary part of road construction so there is no way to eliminate their use. However, getting a more favorable solution in place quickly, and improving safety for the duration of a project, is always a priority. Being able to bridge the gap of a failed bridge with a temporary working bridge in mere days [see 30-hour bridge case study] is a solution most crews and motorists would favor.

Work zone safety is always a concern, especially with road or bridge work that requires lane closures and detours that affect regular traffic patterns and motorist expectations on routes they use regularly. Not to mention motorists’ conformity to obeying traffic signs that warn them of new traffic patterns or speed limit changes. Anytime these situations arise, the risk of road hazards increases for workers and drivers alike. But there is an alternative that helps to remove those risks.

A temporary bridge

With Mabey’s temporary bridges and structural support towers, repair work can proceed while keeping the roads operational and reducing or eliminating the need for detours or lane closures. And temporary bridges also serve as permanent solutions in many cases. Look at some of our featured projects for these applications.
