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.

A new 5-foot sidewalk was added along the south side of the road and portion of the north side, which tied into existing sidewalk at US 301 (SR 43). Due to the addition of sidewalk, some open drainage systems were enclosed with storm sewer and constructed with a shallow swale above the pipe. Permits were received from the Southwest Florida Water Management District (SWFWMD) and U.S. Army Corps of Engineers (USACE).

A Level 1 temporary traffic control plan (TTCP) utilized a flagging operation was required. Single- and multi-use posts were added. Signing and pavement markings included audible-vibratory markings in the non-residential areas. Existing light poles in conflict with the new sidewalk were relocated. The project included utility coordination and the adjustment or relocation of three utility agency owner (UAO) facilities. Protean, along with FDOT staff, met with property owners to coordinate driveway modifications and to establish leasing agreements for parking areas. LAMP survey and subsurface utility engineering were completed by a subconsultant.
