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 entrances 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.
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 winter/spring 2021*:
Mainlane Barrier Work
- Removal of the temporary mainlane construction barrier from Ayers and Everhart began in January 2021 and will continue through summer 2021. Drivers should expect frequent overnight freeway closures to allow the contractor to remove existing barriers and construct new cast-in-place barriers.
Eastbound Mainlane Widening
- The eastbound mainlane widening between Weber and Everhart Road is expected to be complete in early 2021. Drivers should expect daytime/night-time entrance and exit ramp closures during this part of the widening work.
Eastbound Overpass Widening
- Weber Road: Rail installation at the Weber overpass widening is expected in spring 2021. Drivers should expect post rush-hour closures of the intersection, as well as daytime/night-time turnaround closures. Once work at the Weber bridge is complete, the eastbound to westbound turnaround at the Weber overpass will be opened.
- Staples Street: Work on widening the Staples bridge/overpass began in January 2021. The westbound to eastbound turnaround is closed for drainage and retaining wall work. Drivers should expect closures of the intersection after rush-hour, as well as daytime/night-time turnaround closures. The overpass widening is anticipated to be complete in summer 2021.
Proposed Eastbound Ramps
- Weber Entrance Ramp: The existing Weber entrance ramp will close permanently in spring 2021. Drivers will continue on the frontage road, pass through the Weber and Everhart intersections, and may enter the eastbound mainlanes after Everhart. The new Weber entrance ramp is anticipated to open in early summer 2021.
- Everhart Road Exit Ramp: The existing Everhart exit ramp will close permanently in spring 2021. A temporary exit ramp to Everhart will open when the existing ramp closes. The new Everhart exit ramp will be located approximately a quarter mile west of the existing ramp and is anticipated to open in early summer 2021. The new ramp will increase safety and mobility by providing additional distance for exiting vehicles and frontage road traffic to merge and queue while approaching the Everhart intersection. The change also helps reduce traffic conflicts and backups from the intersection onto the SH 358 mainlanes.
- Airline Road Exit Ramp: Work began on the new eastbound exit ramp to Airline Road in early 2021. The new ramp will be located just west of the existing ramp and is anticipated to open in summer 2021.
- Staples Street Drainage Improvements: Drainage work will continue on the eastbound frontage road at Staples Street this winter/spring 2021. Drivers will encounter frontage road and daytime/night-time turnaround closures as crews work in this area.
- Airline Road Drainage Improvements: Drainage improvements at the Airline intersection with SH 358 have paused while the City’s contractor works on the Airline Road project, located on the north side of the intersection with SH 358. TxDOT will continue to coordinate with the City’s contractor to minimize impacts to the public.
- Drivers should expect daytime delays and congestion on the north side of SH 358 at the Airline intersection during the city’s improvement work. Detour options will be provided in the event of an intersection closure.
- More information about the City’s Airline Road project can receive updates at Airline Road Project.
- Mainlane closures are expected in order to remove existing overhead sign bridge structures, install new overhead sign bridge structures, and place new signage for each of the new exit ramp locations. Drivers should anticipate nighttime closures of the eastbound mainlanes, as well as closures to exit and entrance ramps.
High Mast Lighting Structures
- The last two new high mast lighting structures will be installed in late spring 2021. The first is located on the SH 358 westbound frontage road near the Airline Road exit ramp. The second is located on the SH 358 eastbound frontage road at the Weber intersection. The high mast lighting structures will improve lighting and enhance safety. Ramp, intersection, and/or eastbound and westbound frontage road lane closures will be required for the installation of the high mast structures.
Traffic Signal Upgrades
- 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.
- Signal and lighting work will continue weekdays between the hours of 8 a.m. and 4:30 p.m. Intermittent eastbound and westbound frontage road lane closures will be required for the traffic signal work.
* All estimated completion time frames are based on the TxDOT contractor’s latest schedule information and are subject to change.
During project construction, drivers on SH 358 in Corpus Christi may 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. Drivers need to watch their speed in the construction area. Drivers should also be on the lookout for construction workers at all times along the entire SH 358 corridor.
