Minimum Lane Width during construction.
Minimum Lane Width during construction.
(OP)
We are looking to reconstruct a bridge over a turnpike and need to keep the local road open. However,the bridge is narrow and during construction the width of the open lane(signliazed control) might be less than 9'(which we have never done before). Does anyone know is MUTCD has a minimum requirement for this condition?

The sad part is we would like to close the structure as it would be both time and cost effective but the detour for less than 400 cars a day was 4 miles. too far for most people.
Thanks for the information.

Or, how about just detouring trucks?
In my NY State DOT days, we were redecking a bridge on a curve. The bridge designer said a 10' lane was plenty. The construction group said, no, it's on a curve, and the trucks will need more width because the back left wheel will off-track. They called us (Traffic Engr. & Safety) in to cast the deciding vote. I said get some flaggers out there, put cones where the barriers will be and see what happens.
Maintenance ran one of their snowplows through with no problem, but an interstate semi (19 m whgeelbase) came through and squashed a few cones. We put in a truck detour, but left the bridge open to passenger car traffic.
