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 early 2020. 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.  

Activities are planned for Summer 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 late summer 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) to exit to Kostoryz Road/Carroll Lane sooner than is currently required.

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 this summer/early fall:

  • Carroll Lane Overpass: Began in early 2019, with completion anticipated in early fall 2019. 
  • Kostoryz Road Overpass: Began in spring 2019, with completion anticipated in late fall 2019. 
  • Everhart Road Overpass: Scheduled to begin later this summer, with completion anticipated in 2020. 

Eastbound Frontage Road

  • New asphalt pavement is scheduled to be placed in the vicinity of Oakhurst Drive, with completion scheduled in July. 
  • Construction of new sidewalks, curbs, gutters and pavement will begin this summer in the area of Mattress Firm and the Coastal Bend Cancer Center, east of South Staples Street. Completion is scheduled for this fall. 
  • 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 through 4 p.m. Friday afternoons. All businesses and properties will remain accessible at all times.

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 throughout 2019. This work will primarily occur weekdays between the hours of 8 a.m. and 4:30 p.m.

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.
