IH-30 Lake Ray Hubbard Bridge Project

SEMA Completed The IH-30 Lake Ray Hubbard Segment 1 project in Rockwall, TX. The Project includes the stretch of highway from Bass Pro Drive to Dalrock Road. The overall scope of work involved construction of eight lanes on the interstate including continuous frontage roads over lake Ray Hubbard and reconstruction of the Bayside Drive bridge and ramps, as well as the reconstruction of the Dalrock Road interchange & Direct Connect.

Notable statistics of the project highlight its scale and complexity, with construction involving the placement of 185 columns on the eastbound frontage road bridge and 166 columns on the westbound frontage road bridge. With a total bridge deck area of approximately 944,000 square feet, the project also includes over 73,000 square feet of concrete paving. The project marks a significant milestone for TxDOT, supporting initiatives to enhance mobility and infrastructure for the entire region.

Selling Points

The Interstate 30 (IH-30) Expansion Segment 1: Bass Pro Drive to Dalrock Road project represents a piece of a larger infrastructure endeavor that addresses traffic congestion and population growth in the Dallas area, When completed the project will also provide an alternative route across the lake for emergency personnel significantly reducing response times in the area.

Major Achievements

SEMA partnered with Txdot to combine and rephase critical areas on the project to accelerate the work to finish the project ahead of schedule providing the traveling public and Emergency Personnel better access and quicker response times.

Savings

The IH-30 project demonstrated remarkable innovation and contributed to industry standards through the strategic utilization of Flexifloat technology. Working in collaboration with Robishaw Engineering, the SEMA team developed an innovative plan to transport TX70 girders and tractor-trailers to the crane barge assemblies. With the assistance of Steamboat Structures, SEMA’s Project Manager and Construction Manager implemented a lift plan that enabled the utilization of two crawler cranes on the Flexifloat platforms.

A stability analysis conducted by Robishaw ensured the safe operation of the cranes within their rated marine limits, ultimately allowing for the lifting of girders weighing up to 145,000 pounds and as long as 139 feet. With the trailer’s ability to directly access the girder transport, the SEMA team was able to optimize loading, transportation, and unloading processes, facilitating efficient two-crane picks and reducing turn-around times. The innovative approach not only enabled smoother movement of materials but also allowed the drilling contractor to proceed with drilling pier shafts several bents ahead.

Through the integration of this innovative approach, the project achieved unprecedented levels of efficiency, setting new standards for bridge assembly construction, lowering the cost to construct the bridges on the water and fast track the work saving our client time and money.
