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 the 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.  

These activities are planned through summer 2020*:

Eastbound Mainlane and 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 mainlane widening work on the eastbound side of the corridor will allow the addition of a fourth eastbound lane to address this need, matching the existing configuration of the westbound mainlanes in this area.  

The following mainlane overpass widening work is anticipated through summer 2020:

  • Carroll Lane Overpass: Began in early 2019, with completion anticipated in spring 2020.
  • Kostoryz Road Overpass: Began in spring 2019, with completion anticipated in summer 2020.
  • Everhart Road Overpass: Began in late 2019, with completion anticipated in summer 2020.
  • Weber Road Overpass: Anticipated to begin in spring 2020 and finish in fall 2020. 

Drivers may experience periodic nighttime closures at the SH 358 intersections with Carroll Lane, Kostoryz Road, Everhart Road, and Weber Road as crews work to widen overpasses.

New Eastbound Entrance/Exit Ramps 

  • Construction of the new eastbound exit ramp serving Kostoryz Road and Carroll Lane was completed in fall 2019. However, the ramp opening was rescheduled from late 2019 to late spring/summer 2020, when warmer temperatures will allow for the final activities required to switch traffic to the new ramp. Once the new ramp is in operation, the existing exit ramp will be permanently closed and removed.
  • Work on the new eastbound exit ramp serving Weber Road began in June 2019. The opening of the new ramp is anticipated in spring 2020.
  • Work on the new eastbound entrance ramp from Kostoryz Road is anticipated to begin in spring 2020 and finish in summer 2020.

Eastbound Frontage Road

  • Bay Ltd. will continue work on the left side of the eastbound frontage road, focusing on ramp reversal acceleration and deceleration lanes, drainage improvements, and retaining walls at each of the overpasses from Kostoryz Road to Weber Road.
  • This work will continue to require various frontage road lane closures, including potential temporary closures of various driveways and side street intersections, as well as turnarounds. The work will primarily occur between the hours of 9 p.m. Sunday evenings and 4 p.m. Friday afternoons. All businesses and properties will remain accessible at all times.

Airline Road Drainage Improvements

  • Drainage improvements at SH 358 and Airline Road are expected to begin in early 2020, with work anticipated to be complete in spring 2020.
  • This work will require a northbound right lane closure on Airline Road and a right lane closure on the eastbound frontage road, and will primarily occur Sunday through Thursday between the hours of 9 p.m. and 6 a.m.


Mainlane Signage

  • Work began in fall 2019 to replace the overhead signs for the new eastbound exit ramp serving Kostoryz Road and Carroll Lane.
  • This work will continue to require periodic and ongoing mainlane and frontage road closures in both directions between Carroll Lane and Weber Road and is expected to be complete in spring/summer 2020.

Traffic Signal and Lighting Upgrades

  • Traffic signal work and the installation/relocation of high mast lighting structures will continue at various locations along the SH 358 corridor through early 2022. Many intersections will receive new poles and/or traffic lights.
  • Traffic signal upgrades are ongoing between Leopard Road and Waldron Road.
  • Four high mast lighting structures will be installed in spring/summer 2020 between Nile Drive and Airline Road.
  • This work will continue to occur weekdays between the hours of 8 a.m. and 4:30 p.m., and will require periodic eastbound and westbound frontage road lane closures.

* All estimated completion time frames 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 and westbound frontage road lanes, and intersections/turnarounds 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.
