Since 1974, Kopplow Construction has helped shape San Antonio’s commercial landscape. In 2026, our team spent more time in the northeast, up Interstate 35. As New Braunfels, Seguin, Schertz and Cibolo keep growing, businesses, clinics and employers that follow new residents need buildings, and they need them on schedule.

Here’s a look back at our year, and at the trends we expect to keep the corridor busy in 2027.

Our 2026 at a Glance

Our work in the corridor builds on a track record that includes the WellMed medical building in Seguin and the Schertz Medical Office Building. Projects like these show how healthcare and professional services move in right behind residential growth.

• WellMed Seguin Medical Building Construction
• Environmental Systems Research Institute (ESRI)
• Schertz Medical Office Building

What’s Driving Growth on I-35:

New Braunfels: Still One of the Fastest-Growing Places in Texas

Comal County’s population has grown nearly 28% since 2020, and Guadalupe County is climbing too. Steady population growth like that brings sustained demand for medical offices, retail centers, schools and service businesses up and down the I-35 corridor.

Plan for a welcoming environment and a good patient experience

2026 has been one of Seguin’s biggest years for industrial investment. In July, the city approved KTH Texas to build a $127 million automotive manufacturing facility off FM 78, bringing in more than 170 new jobs. This plant anchors the Seguin Exchange, a 544-acre mixed-use development planned between FM 78 and I-10. Nearby, LCI Industries’ $80 million, 400,000-square-foot Ranch Hand plant at TriPoint Logistics Center was scheduled to deliver in 2026. New jobs at this scale create demand for the clinics, restaurants, offices and retail that serve the people who fill them.

Schertz–Cibolo: Industrial Momentum and the Infrastructure to Support It

Schertz has kept its run of industrial growth going in 2026. Titan Development broke ground on a new 391,040-square-foot building at Schertz35 Business Park, and a 325,000-square-foot speculative cold-storage warehouse broke ground near FM 2252, less than half a mile from I-35. Cibolo approved a wastewater master plan in early 2026, and Schertz backed a sewer extension to open more industrial land. Both are signs that the cities are building the utility capacity on which future development will depend.

The I-35 Highway Itself

The $1.5 billion I-35 NEX Central project, which adds elevated lanes along 9.5 miles of I-35 from I-410 to FM 3009 in Schertz, was about a year from completion as of late summer. TxDOT expects the first major section to open in early 2027. In July, TxDOT also broke ground on the final $182 million segment of the Loop 1604 North Expansion, which will link Loop 1604 to I-35 NEX. Better access makes every site along the corridor more valuable.

What It Means for Owners Planning to Build in 2027

Three takeaways from what we saw this year:

1. Services follow jobs and rooftops: Industrial and residential growth is coming first, followed by medical, retail, office and hospitality projects close behind and the owners who plan early get the best sites.
2. Infrastructure shapes the timeline: Utility capacity, road work and permits vary from city to city along I-35. Bringing in a contractor during pre-construction can help address these factors before delays become a problem.
3. Local experience matters: Building in New Braunfels is different from building in Seguin or Schertz. Knowing the jurisdictions, subcontractors and site conditions in each city keeps projects on budget.
