Relieving congestion in Texas

The convergence of State Highways 114 and 121 in the Dallas/Fort Worth Metroplex. These multi-lane freeways merge for two miles just north of Dallas/Fort Worth (DFW) International Airport, forming the nexus of a super-interchange of seven freeways.
TxDOT initiated a major transportation study for the Dallas/Fort Worth Metroplex in response to significant traffic growth where these freeways – 114 East and West; 121 North and South; Interstate Highway 635; State Highway 360; and International Parkway – pass through the 114/121 'Funnel.'
The resulting $650 million construction project includes adding main lane and managed lane capacity; construction or modification of four freeway-to-freeway multilevel interchanges; three segments of collector-distributor roadways; six pairs of braided ramps, numerous cross-street interchanges and a connection to regional rail service.
