I-35
I-35 is the county's major interstate corridor and carries regional traffic through the New Braunfels area. It connects the San Antonio and Austin regions and includes entrance ramps, exit ramps, frontage roads, and multiple interchanges.
For a new driver, the key skill is managing speed and lane position while entering and leaving the interstate. Drivers should identify their exit early instead of making a last-second lane change.
TxDOT's I-35 NEX program includes improvements through Comal County, with the North project extending from the Guadalupe County line to FM 1103. The 2026 Unified Transportation Program lists an estimated FY 2026 through FY 2029 letting period for the Comal County North project.
SH 46
SH 46 is a major east-west corridor through the county. It connects the I-35 area with US 281 and continues toward other regional communities.
TxDOT is studying and planning major improvements along SH 46 between I-35 and I-10. The Comal County portion includes proposed overpasses and changes around I-35, FM 1101, Alves Lane, and Business 35.
Students practicing in this corridor should expect that roadway layouts can change as projects advance. Temporary signs, lane markings, turn restrictions, and construction traffic control take priority over an older understanding of the route.
US 281
US 281 is an important north-south route through western and northern parts of the county. TxDOT has proposed improvements to US 281 in Comal County, including a long-term plan to convert the section from the Bexar County line to SH 46 into a freeway with frontage roads.
This makes US 281 especially useful for teaching the difference between divided highway driving and freeway-style travel. Drivers should understand how main lanes, frontage roads, entrance ramps, exits, turnarounds, and intersections can interact.
FM 306
FM 306 serves the Canyon Lake area and connects with other major routes in the county. County and regional transportation planning has identified improvements along portions of FM 306, including work around FM 2673 and bridges over the Guadalupe River.
Drivers should be prepared for a mixture of developed areas, intersections, bridge approaches, and less urban sections of roadway.
FM 1101
FM 1101 connects the New Braunfels area with the surrounding regional road network. It also appears in TxDOT's SH 46 improvement plans, where an interchange or overpass is proposed at the SH 46 corridor.
A student using this route can gain experience with turning movements, highway transitions, and changing traffic-control patterns.
FM 1863, FM 3009, FM 311, and FM 2673
These Farm-to-Market routes help connect residential, rural, and regional areas. County transportation recommendations include improvements on FM 1863, FM 3009, FM 311, and FM 306.
For new drivers, these roads reinforce an important lesson: a road does not need to be an interstate to require careful speed management. Rural and suburban FM routes can have changing lane widths, intersections, shoulders, curves, and varying levels of development.
