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 Road, including “reversing ramps” between Weber Road and South Staples Street to reduce traffic backups on the freeway mainlanes as exiting vehicles approach signalized intersections. 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.
  • Widen and construct new auxiliary, or "merge," lanes on the eastbound mainlanes and frontage road between Ayers Street and Nile Road 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 Road to enhance safety.
  • Construct new sidewalks between Ayers Street and Nile Road 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 and Current Activities

The project is being constructed in ten phases, and is expected to be complete in the fall of 2021. Phase 1 activities began in January 2018 and are scheduled to be complete by August 2018. Some Phase 2 activities began in March 2018, with the most significant Phase 2 work scheduled to begin this summer and last until April 2019. 

The following activities are planned for Summer 2018:

SH 358 Mainlanes and Eastbound Frontage Road

  • Phase 1 work will continue to fill in the gaps between the eastbound and westbound mainlanes on the overpass bridges at Kostoryz Road, Carroll Lane and Weber Road. 
  • The Phase 1 activities to prepare for a traffic shift to the inside shoulders and mainlanes near Kostoryz Road is complete, allowing crews to begin Phase 2 work on the outside mainlanes and the Kostoryz Road exit ramp relocation.
  • Various closures on the eastbound and westbound mainlanes, as well as the intersections underneath the mainlane bridges from Kostoryz Road to Weber Road, are expected to continue weekly throughout the summer, primarily between the hours of 9 p.m. and 6 a.m. Sunday evenings through Friday mornings.
  • Various frontage road closures near Kostoryz Road are expected to continue weekly throughout the summer, primarily between the hours of 9 p.m. and 6 a.m. Sunday evenings through Friday mornings. All driveways will remain open and accessible to the public.

Traffic Signal Upgrades

Traffic signal work will continue at various intersections along the SH 358 corridor through the summer and into the fall. This work will primarily occur weekdays between the hours of 6 a.m. and 9 p.m.

Information about future phases is available on the Project Fact Sheet and will be updated on this webpage as construction progresses. 

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 Road is reduced to 55 miles per hour on the mainlanes and 40 miles per hour on the eastbound frontage road.
