Approximately 45,000 vehicles travel this section of the highway each day. The project area is part of a major northbound hurricane evacuation route and serves as a southbound “gateway” into Corpus Christi.
The project is approximately 2.3 miles long and construction is expected to last 5.5 years.
- Widening the I-37 mainlanes to four lanes in each direction with widened shoulders
