This 9.5-mile transportation improvement project spanning from I-410 North in Bexar County to FM 3009 in Guadalupe County will have three elevated lanes in both directions—including high-occupancy vehicle lanes—and will incorporate flyovers to I-410 North and Loop 1604 West.
With the start of the project, lanes along I-35 will be temporarily closed for geotechnical and drilling work.
I-35 NEX Central is the first of three expansion projects along a 20-mile stretch of I-35 from just north of AT&T Center Parkway to FM 1103. The complete project work is estimated to be completed in 2027.
Project updates and information can be found here.
