The Texas Department of Transportation (TxDOT) is proposing to construct an extension to Spur 399 from US 75 south of McKinney to US 380 east of McKinney in Collin County. The proposed project would accommodate a six to eight-lane freeway with frontage roads on each side in most areas to improve north-south mobility and improve connectivity between the eastern portion of Collin County and destinations south of McKinney. The typical proposed right-of-way (ROW) would be approximately 400 feet wide, with the minimum and maximum ROW width ranging from 165 feet to 696 feet, respectively. Depending on the location, the typical freeway section would consist of four 12-foot-wide travel lanes in each direction with 10 to 17 foot wide inside and outside shoulders and 2 lane (each 12-feet-wide), one-way frontage roads on either side of the mainlanes. Shared-use paths built along the outside of the frontage roads would provide bicycle and pedestrian accommodations and support multi-modal access. The total proposed ROW acreage is estimated at 366.1 acres. The proposed project passes through the City of McKinney and College County and is near the town of Fairview.
