Purpose 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, Texas.

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 (SUPs) 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 Collin County and is near the Town of Fairview.

The proposed project would cross over a portion of the Wilson Creek Greenbelt, owned by the City of McKinney, east of State Highway (SH) 5. The new location freeway would be constructed on a bridge over the park land. The piers supporting the bridge would touch down within the park property but would not affect the trails and other park amenities. TxDOT anticipates making a De Minimis determination for this use under Section 4(f) of the Department of Transportation Act of 1966. Public comment on the effects of the proposed project on the activities, features, or attributes of the Wilson Creek Greenbelt may be submitted as described below.

The proposed project would, subject to final design considerations, require additional ROW and potentially displace seven residences and two business structures.

Accessibility The public hearing will be conducted in English. If you need an interpreter or document translator because English is not your primary language or you have difficulty communicating effectively in English, one will be provided to you.
