In January 2018, TxDOT initiated construction of improvements to enhance safety and increase mobility along SH 358 (South Padre Island Drive) in Corpus Christi, Texas (Nueces County). The four-year project consists of multiple phases and is located along SH 358 from just north of Leopard Street to just east of Flour Bluff Drive.

This 15-mile project includes the following improvements to address safety and mobility:

  • Reconstruct several eastbound entrance and exit ramps between Ayers Street and Nile Drive, including:
    • “Reversing ramps” between Weber Road and South Staples Street. This involves converting existing entrance ramps into exit ramps and vice-versa, similar in design to the previously “reversed” westbound ramps between Weber Road and Airline Road.
    • Relocating the exit ramps serving Kostoryz Road/Carroll Lane and Weber Road.
    • These ramp reversals and relocations will increase safety and mobility by providing additional distance for exiting vehicles and frontage road traffic to merge and queue while approaching signalized intersections.
  • Widen and construct new auxiliary, or "merge," lanes on the eastbound mainlanes and frontage road between Ayers Street and Nile Drive to allow drivers entering and exiting the highway to safely merge with other traffic.
  • Improve lighting and reconstruct existing mainlane median barrier between Ayers Street and Nile Drive to enhance safety.
  • Construct new sidewalks between Ayers Street and Nile Drive to improve safety and access for pedestrians and bicyclists.
  • Improve traffic signal timing and connectivity along the eastbound frontage road to increase mobility.
  • Improve Intelligent Transportation Systems (ITS) along the entire corridor to provide drivers and emergency responders with accurate, up-to-the-minute traffic information.

Project Phasing

The project is being constructed in ten phases and is expected to be completed in spring 2022. More information on the activities associated with each phase and the project timeline can be found on the project fact sheet and the detailed SH 358 Improvements Presentation.  

The activities are planned through the end of 2019:

New Eastbound Exit Ramp to Kostoryz Road & Carroll Lane

  • The new eastbound exit ramp serving Kostoryz Road and Carroll Lane is anticipated to open in fall 2019. Once the new ramp is in operation, the existing exit ramp will be closed to traffic and removed. This ramp relocation will improve safety and mobility on both the eastbound SH 358 mainlanes and frontage road by allowing exiting drivers more space to merge with frontage road traffic and queue at the Kostoryz intersection.
  • The new ramp location will require drivers to merge with traffic entering from SH 286 (Crosstown Expressway) and to exit to Kostoryz Road/Carroll Lane sooner than is currently required.
  • New signage is being installed at the new eastbound exit ramp, which will require some mainlane and frontage road closures in both directions.

Eastbound Mainlane Overpasses

One of the primary purposes of this construction project is to improve mobility along the heavily-traveled eastbound SH 358 mainlanes through the heart of Corpus Christi’s main commercial corridor. Current and future work to widen several eastbound mainlane overpasses will allow the addition of a fourth eastbound mainlane to address this need, matching the existing configuration of the westbound mainlanes in this area. The following overpass widening work is anticipated through the end of 2019:

  • Carroll Lane Overpass: Began in early 2019, with completion anticipated in late 2019.
  • Kostoryz Road Overpass: Began in spring 2019, with completion anticipated in late 2019.
  • Everhart Road Overpass: Began in fall 2019, with completion anticipated in spring 2020.

Drivers may expect periodic closures at the SH 358 intersections with Carroll Lane, Kostoryz Road, and Everhart Road as crews work on widening these overpasses. The eastbound-to-westbound and westbound-to-eastbound turnarounds at Kostoryz Road and Carroll Lane will also be closed for an extended period during the overpass widening activities. Drivers may make left turns at these intersections, which will remain open.

Eastbound Frontage Road

  • Construction of new sidewalks, curbs, gutters, and pavement along the eastbound frontage road between Everhart and Staples is expected to be complete in late 2019.
  • Widening of the eastbound frontage road between Kostoryz and Airline Road has been ongoing since early 2019, with completion anticipated in spring 2020.
  • This work will continue to require various frontage road lane closures, including potential temporary closures of various driveways and side street intersections, primarily between the hours of 9 p.m. Sunday evenings and 4:30 p.m. Friday afternoons. All businesses and properties will remain accessible at all times.

Mainlane Signage

  • Work began in September 2019 to replace the overhead sign structure between Weber Road and Carroll Lane on the westbound mainlanes, in preparation for the installation of new signage for the new eastbound exit ramp serving Kostoryz Road and Carroll Lane. The work at this location is expected to continue through fall 2019.   
  • This work will require ongoing closures of the left westbound frontage road lane from just east of the Weber Road entrance ramp to Carroll Lane.

Airline Drainage Improvements

  • Drainage improvements at SH 358 and Airline Road are expected to begin in fall 2019, with completion anticipated in late 2019. The work will require a northbound right lane closure on Airline and a right lane closure on the eastbound frontage road. This work will primarily occur Sunday through Thursday between the hours of 9 p.m. and 6 a.m. nightly.

Traffic Signal and Lighting Upgraes

  •  Traffic signal work and the installation/relocation of high mast lighting structures will continue at various locations along the SH 358 corridor throughout 2019.
  •  This work will primarily occur weekdays between the hours of 8 a.m. and 4:30 p.m.

* All estimated completion time frames are based on Bay Ltd.’s September 2019 schedule update and are subject to change.

Traffic Updates

During project construction, drivers on SH 358 in Corpus Christi could potentially experience delays due to temporary closures of the highway mainlanes, eastbound frontage road lanes, and intersections underneath the mainlanes. Most closures will take place during off-peak hours, typically between 9 p.m. and 6 a.m., though the times and days may vary. The speed limit within the construction zone from Ayers Street to Nile Drive is reduced to 55 miles per hour on the mainlanes and 40 miles per hour on the eastbound frontage road.
