 I-35/SH 6 

 Loop 360 

 Interchange  

The intersection of IH 35 and SH 6/Loop 340 serves as a major gateway of the greater Waco area. IH 35 is one of two north-south interstate highways traversing Texas and has become a major international trade route with truck traffic accounting for 25 to 30 percent of all daily traffic. SH 6 and LP 340 are heavily traveled freeway facilities and together with IH 35, form the major travel ways for businesses and residents in the Waco area. Features in the vicinity of the interchange include one of the area’s largest retail developments, several industrial developments, and a state-of-the-art hospital.

CP&Y led the advanced planning and PS&E design for a multi-phase redevelopment of IH 35 at SH 6/Loop 340.

 

Phase I included the design of frontage roads on the Northwest corner of the interchange to accommodate increased traffic flow for the opening of one of the largest retail developments in the area’s history.

 

Phase II involved the design and construction of a multi-level, fully directional interchange. This phase included the design of the SH 6/Loop 340 main lanes, IH 35 and SH 6 frontage roads, direct connectors, loop ramps, and entrance/exit ramps with an overall construction cost of approximately $48 million.

 

Phase III encompassed the rebuilding of approximately 3.5 miles of IH 35 main lanes and frontage roads from New Road to FM 2063. It also involved substantial operational improvements of the ramps, FM 2063/2113 interchange, and the construction of direct connectors for IH35 and FM 2113 with a total construction cost of approximately $100 million.

Through close coordination with District staff, CP&Y provided the State with a design solution that met their allotted design schedule, achieved the purpose and needs of the project, and provided the Waco area with a facility that will meet the growing traffic demands of the area far into the future.
