minimum offset for concrete traffic barrier
(OP)
What is the minimum offset for concrete traffic barrier in a work zone application?
I have a 6 lane divided interstate bridge replacement project where the traffic will be shifted on to a single existing bridge while the proposed bridge is constructed and the opposing lanes will be separated by concrete traffic barrier. The work zone speed limit is 55 mph and the ADT is 50000. In the lane shift area the existing lanes will be narrowed from three 12-foot lanes in each direction to three 10-foot lanes in each direction. My question is how close to the outside lane line can I place the concrete traffic barrier?

If you want to look at safety, the new RSAP software will help calcuate expected crash costs. It's on the Transportation Research Board website
