CORPUS CHRISTI, Texas — The SPID ramp reversal project will reach its first milestone Tuesday, Oct. 15. The newly constructed Kostoryz Road/Carroll Lane eastbound exit ramp opens to traffic.
The new ramp is about one-quarter mile west of the existing ramp, so drivers must be prepared to exit for Kostoryz/Carroll sooner than is currently required.
To prepare for the opening of the new ramp various overnight mainlane, ramp and frontage road closures will be required as crews relocate barriers, add new striping, replace signage and implement the traffic switch.
The existing Kostoryz/Carroll exit ramp will close permanently at 9 p.m. Sunday, Oct. 13.
All SH 358 eastbound mainlanes also will close overnight from 9 p.m. to 6 a.m. Sunday and Monday. Drivers headed eastbound will be required to use the Ayers Road exit and detour signs will be in place. All mainlanes will reopen during the day. Once the new exit ramp is open, crews will demolish and remove the old SH 358 Kostoryz/Carroll exit ramp.
This is the first of several major traffic switches for the SH 358 ramp reversal project. The $50 million project to improve a 15-mile section of SH 358 began construction in January 2018 and is expected to be complete in the spring of 2022.
The new Kostoryz/Carroll ramp relocation will increase safety and mobility by providing additional distance for exiting vehicles and frontage road traffic to merge and queue while approaching the Kostoryz intersection, reducing traffic conflicts and backups from the intersection onto the SH 358 mainlanes.
All work is weather permitting. A detailed list of closures related to the traffic switch will be announced separately.
