Project Overview

The project on SH-99 beginat the end of 4-lane section south of SH-59 junction and extends south approximately 8 miles to EW County Road 134. Ultimately, a 4-lane divided facility will be provided by adding two additional lanes parallel to the adjacent roadway. The proposed improvement includes two phases of construction. Phase 1 will consist of constructing a new two-lane facility for southbound traffic on an offset alignment to the west, with two 12-foot wide driving lanes, a 4-foot wide inside shoulder and a 10-foot wide outside shoulder. Phase 2 will consist of the resurfacing of the existing facility. The median width for this ultimate divided facility will vary from 34 to 52 feet and include median openings every half mile.

A portion of the project from south of 1st Street to 400 feet north of EW128 Road will consist of four (4) 12-foot wide driving lanes with a 20 foot wide paved median and foot wide paved outside shoulders. 

The existing roadway and bridges will remain open during the construction of the new southbound alignment.
