IH 10/SS 330 Ramp Reversal
SS 330 to Thompson Rd
The need for the proposed I-10 from Spur 330 to Thompson Road Roadway Improvement Project is to limit heavy truck traffic on Thompson Road by offering I-10 eastbound access from northbound Spur 330.
The proposed I-10 from Spur 330 to Thompson Road Roadway Improvement Project includes the following: removal of the existing entrance ramp to I-10 eastbound, removal of existing I-10 eastbound frontage road pavement (to remove the two curves in the frontage road), construction of a new entrance ramp approximately 0.40 mile east of the existing Spur 330 southbound entrance ramp to I-10 eastbound, reconstructing and straightening of the I-10 eastbound frontage road to accommodate a new entrance ramp to I-10 eastbound, and construction of an auxiliary lane on the I-10 eastbound mainlanes between Spur 330 and Thompson Road to provide easy access to the I-10 eastbound mainlanes for traffic entering I-10 from the proposed entrance ramp as well as for traffic exiting the I-10 eastbound mainlanes to Thompson Road.
The purpose of the proposed project is to provide vehicular traffic easy access to I-10 eastbound while traveling on Spur 330 northbound or southbound by relocating the I-10 eastbound entrance ramp within the project limits. Traffic entering the I-10 mainlanes and exiting the mainlanes for Thompson Road would be accommodated by an auxiliary lane constructed along the I-10 mainlanes within the project limits. The removal of the two curves along the I-10 frontage road would promote improved safety while still providing access to the wastewater treatment facility located along the eastbound frontage road within the project limits. The proposed project would be constructed within the existing ROW; no additional ROW is required for the implementation of this proposed roadway improvement project.
