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 complete in summer 2022. More information on the activities associated with each phase and the projected timeline can be found on the project fact sheet and the detailed SH 358 Improvements Presentation.  

These activities are planned through fall 2020*:

Eastbound Mainlane Widening

  • In late 2020, drivers can expect driving on the new, right eastbound mainlane between the Kostoryz Road and Weber Road exit ramps, as well as the widened Kostoryz and Weber bridges. There will be numerous eastbound freeway closures to prepare for the opening of the completed mainlane. 
  • Work will continue on the eastbound mainlane widening between Weber and Everhart Road. Crews will focus on ramp reversal acceleration and deceleration lanes, drainage improvements, and building retaining walls at the Weber and Everhart overpasses. Drivers should expect daytime/night-time exit ramp and turnaround closures for retaining wall construction.

Eastbound Overpass Widening

  • Beam installation is scheduled for the Weber overpass in late 2020 to accommodate the overpass widening. Drivers should expect closures of the intersection after rush-hour, as well as daytime/night-time turnaround closures for bridge and retaining wall construction.

Proposed Eastbound Entrance Ramp from Kostoryz Road

  •  Work continues on the new eastbound entrance ramp from Kostoryz Road. The new ramp will be located further east of the existing ramp and is expected to be opened in fall 2020.

Proposed Eastbound Entrance Ramp from Everhart Road

  •  Work continues on the new eastbound entrance ramp from Everhart Road. The new ramp will be located further east of the existing ramp and is expected to be opened in late 2020.

Mainlane Sign

  • New overhead signage for the Kostoryz Road/Carroll Lane exit and the Weber Road exit will be installed this fall/late 2020. Full freeway closures are expected to install overhead sign bridge structures, and single right mainlane closures are anticipated to allow crews to install cantilever overhead sign structures.

Eastbound Frontage Road Drain

  • Drainage work will begin on the eastbound frontage road at Staples Street this fall/late 2020. Drivers will encounter single lane closures on the frontage road, as well as daytime/night-time turnaround closures.

Traffic Signal and Lighting Upgrade     

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

* All estimated completion time frames are based on the TxDOT contractor’s latest schedule information and are subject to cha here

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. 

Please monitor electronic message signs near the construction site for daily updates, as well as Drive Texas and the Corpus Christi District's Twitter feed. Weekly traffic updates are also available for viewing here. Sign up to receive these updates here.
