SEPARATING TRAFFIC
CHANGES ON THE WAY
The I-35 North project will make several changes to I-35 and the surrounding area, including adding a new nontolled high-occupancy vehicle lane in each direction along the length of the project.
High-occupancy vehicle lanes will allow vehicles with two or more riders to use a separate managed lane. The number of lanes varies across the length of the road.

by vehicles with more than two peo- ple, such as individuals carpooling and buses. This will result in 2-6 minutes saved for regular lane users and 30-36 minutes saved for HOV lane users during peak tra c times, according to TxDOT. The project will also add a lane to the north- and southbound frontage roads along the length of the project. Roughly 18 miles of shared-use paths will be built beside most of the I-35 frontage road for use by pedestrians and cyclists. Additionally, the I-35 North proj- ect will reconstruct six bridges with pedestrian and bicycle paths at Grand Avenue Parkway, Wells Branch Park- way, Howard Lane, Walnut Creek, Braker Lane and Rundberg Lane. Bypass roads will also be built near several intersections to allow drivers to bypass busy areas. Along with a new bridge, TxDOT will build a diverging diamond interchange at Wells Branch Parkway and I-35, Wheelis said. The interchange allows large amounts of turning tra c to turn at once by diverting drivers to the opposite side of the road for a short dis- tance. This interchange will run under the bridge, allowing cross-street tra c to enter I-35 more easily. “With [these interchanges], you can move more vehicles through a single signal cycle than a traditional inter- section, and that helps move a lot of left-turning tra c,” Wheelis said. While TxDOT representatives maintain the I-35 overhaul will bene- t motorists when complete, others remain unconvinced. Rethink35 is a volunteer-based organization with chapters from San Antonio to Georgetown dedicated to protesting the I-35 expansion projects. Round Rock chapter founder Ben Berg said the project will not pay o in the way public o cials have promised.
Number of lanes
DIVERGING DIAMOND The Texas Department of Transportation will construct a new diverging diamond under I-35 at Wells Branch Parkway, allowing two lanes of tra c to temporarily shift across the opposite side of the road to move more tra c at once. A
