Bridgefarmer designed 35% of this $1B project with a scope including full design of roadway, bridge, drainage, TCP, utility conflict resolution, retaining walls, managed lanes, and grading. Relevant to the SH 360, this project was delivered as a design-build that involved freeway/ city street interchanges, heavy drainage, and OnCor overhead transmission coordination.
Bridgefarmer’s scope was the west segment in Grapevine, TX. This included 2 miles of SH 114 with managed lanes (varying from 6 lanes to 10 lanes); 1.4 miles of SH 121 improvements; Urban Diamond interchanges at FM 1709, W.D. Tate, and Main St.; a partial cloverleaf interchange at SH 26;
a direct connect (DC) interchange with SH 26 with DC lengths of approximately 5,000 ft.; a DC interchange with SH 121 with DC lengths
of approximately 7,000 ft. and 8,000 ft .; 33 retaining walls; 8,200 ft. of
city streets; frontage roads; storm drain, detention, multiple large
culvert crossings including 1 bridge class culvert; grading; pavement;
22 bridges including 9 bridges crossing a railroad; and DFW flight ceiling coordination (FAA part 77 contours).
The project scope included all disciplines of design and construction activities:
MOT, utilities, right of- way, hydrology & hydraulics, structures, grading, paving
design, retaining walls, pavement markings, signing, illumination, ITS and signals requiring Bridgefarmer to heavily coordinate design.
