Project Description

The Alamo Regional Mobility Authority in partnership with the Texas Department of Transportation (TxDOT) propose to improve Loop 1604 between Bandera Road (State Highway 16) eastward to Interstate 35, a distance of approximately 22.8 miles.

The proposed improvements are being evaluated through an Environmental Assessment (EA). The environmental review, consultation, and other actions required by applicable Federal environmental laws for this project are being, or have been, carried-out by TxDOT pursuant to 23 U.S.C. 327 and a Memorandum of Understanding dated December 16, 2014, and executed by the Federal Highway Administration and TxDOT.

The proposed project would improve mobility and reduce congestion by adding two buffer separated express lanes in each direction along Loop 1604. Eight new flyover direct connectors would be added at the existing IH 10 interchange for the tolled express lanes. Due to the widening and restriping, existing ramps would be modified along Loop 1604 and IH 10. Ramps are proposed to be reversed in order to convert diamond intersections into “X” intersections, making a larger portion of the frontage road more accessible and greatly increasing cross street approaches for a ramp exiting to the frontage road. Turnarounds would be added to all cross streets that do not currently have one (except Tradesman) as well as right and left turn lanes along the frontage road approaches. As warranted, the addition of lanes through the intersections are included where ROW acquisition would not be required.

The proposed improvements could include improved transit services through the provision of additional lane space for transit vehicles and other registered and tagged high occupancy vehicles. A new sidewalk is proposed throughout the project limits where there are gaps in sidewalks and worn foot paths. Bicycle access was deemed sufficient due to the existence of shoulders along the frontage roads throughout the project limits.
