This 9.5-mile transportation improvement project, 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 (HOV) lanes, and will incorporate flyovers to I-410 North and Loop 1604 West. 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.

Message from TXDOT:

The photo above shows the first column completed on the I-35 NEX Central project located in the area of southbound I-35 and Farsight Drive between the mainlanes and frontage road. This is just one of over 1,140 columns that will support the future elevated lanes. Soon you will see more columns being formed along southbound I-35 and eastbound Loop 1604 as construction progresses.
