  Loop 1604 North Expansion Project
Project Update | July 2021
We’re gearing up for construction, and that means keeping you informed about upcoming activities, potential impacts and what to expect.
Project Update
After project kickoff in May, the project team remained busy during the month of June prepping the construction site. Night work was performed with alternating lane closures that allowed for concrete barrier placement and striping along the first segment of the corridor from SH 16 (Bandera Road) to I-10.
Construction truck entrances and exits were established to safely control the movement of the construction vehicles needed along the project. The contractor has also started work on the drill shafts and footings that will be the support system for the direct connector bridge approaches for Segment 1.
The project team's current focus is constructing the eastbound to westbound direct connector approach.
Upcoming Work
Upcoming work planned in July will include continued work on the eastbound to westbound direct connector approach. Additionally, the following work will begin:
- Foundation work for the bridge widening over Bandera Road (westbound) will kick off.
- Temporary signals will be placed at Hausman Road and Kyle Seale Parkway to allow for the construction of the new bridges at the intersection.
- Roadway excavation necessary to prepare the areas for the improvements on the roadway will begin.
- Work will get underway on the Intelligent Transportation Systems (ITS) and High Mast Illumination (HMI) to further improve safety along the corridor. The ITS components that will be used on the corridor include closed-circuit television (CCTV) cameras, Fiber Optic Cable installation for CCTV cameras and DMS (Dynamic Message Signs) to be used for TransGuide, the Traffic Management Center.
- Storm water drainage work and movement of gas utilities will be ongoing as well.
TxDOT will continue to provide advance notification to stakeholders directly impacted by this upcoming work.
Similar to last month, TxDOT will announce updated lane closures as soon as they are identified and maintain open communication throughout the duration of project.
As always, all construction work is dependent upon weather conditions.
 About the Project
The Loop 1604 North Expansion Project involves 23-miles of planned transportation improvements that are designed to increase mobility, reduce congestion and enhance safety along one of the most congested corridors in the state. The project includes the following planned improvements:
- Expanding Loop 1604 from a four-lane expressway to a ten-lane expressway including one high-occupancy vehicle (HOV) lane in each direction.
- Reconfiguring the layout of auxiliary lanes and entrance and exit ramps.
- Removing the cloverleaf connectors. Replacing the cloverleaf interchange at I-10/Loop 1604 with a five-level direct connect interchange.
- Adding direct connectors.
- Converting the current signalized frontage road intersections at I-10 /Loop 1604 interchange into a partial roundabout system to allow continuous traffic movement.
- Upgrading Blanco Road and Loop 1604 to an innovative Diverging Diamond Intersection (DDI).
- Adding improvements and accommodations for bicyclists and pedestrians, water quality protection, and other highway features.
Once complete, the planned project improvements will reduce congestion, improve mobility and enhance safety by:
- Decreasing future travel times by as much as 80 minutes.
- Increasing capacity with non-toll general purpose and HOV lanes.
- Integrating multimodal improvements with the construction of continuous sidewalks and bicycle accommodations.
- Creating a fully directional, five-level interchange at I-10 and Loop 1604.
