Protean Design Group designed plans to mill and resurface 1.98 miles of SR 674, an urban minor arterial two-lane undivided roadway with paved shoulders and both open ditch and closed drainage systems. The paved shoulders were striped as bicycle lanes. Design and posted speeds varied from 40 to 45 MPH. Friction Course 12.5 (FC-12.5) was utilized.

A new 5-foot sidewalk was added along the length of the project and tied into existing sidewalk at US 301 (SR 43). Due to the addition of sidewalk, some open drainage systems were converted to curb and gutter. Other minor drainage improvements were also incorporated. Permitting was received through the Southwest Florida Water Management District (SWFWMD) and U.S. Army Corps of Engineers (USACE).

A Level 1 temporary traffic control plan (TTCP) was utilized and a flagger was required. Single- and multi-use posts were added. Signing and pavement markings included audible-vibratory markings in the non-residential areas. We modified the existing lighting photometrics to accommodate the addition of the sidewalk. Two utility agency owners (UAOs) were relocated and close coordination ensured this was a smooth process. We met with property owners to establish leasing agreements for parking areas. A LAMP survey and subsurface utility engineering was completed by a subconsultant.
