Bridge width, exclusive of sidewalks, shall be equivalent to the existing or, if wider, proposed approach roadway (i.e., traveled way and any shoulders) width. In the absence of shoulders, the bridge width shall be 4 ft. (2 ft. per side) wider than the approach traveled way width. Greater bridge widths may be considered if future expansion of the facility will occur within the first half of the expected life of the bridge improvement, shared-use lanes will be constructed immediately adjacent to the roadway, or to facilitate construction.
