1. RM 620 at Anderson Mill intersection improvements
The Texas Department of Transportation is planning to build an overpass at the intersection of RM 620 and Anderson Mill Road. The project is part of the agency’s long-term plans to improve mobility along RM 620. TxDOT is still designing the improvements, but RM 620 would pass over Anderson Mill. In May, the Capital Area Metropolitan Planning Organization awarded $25 million in state and federal funding for the project.
Timeline: TBD
Cost: estimated at $25 million

Latest updates

1. Improving Anderson Mill Road
In September, city staffers finished the design on improvements to Anderson Mill Road between Spicewood Parkway and US 183. Improvements include adding a center turn lane and medians, extending the right-turn lane to US 183 and a new lane configuration at Olson Drive.
Timeline: 2020-21 (construction)
Cost: $7.26 million
Funding sources: 2016 Mobility Bond, Quarter Cent Fund

2. Improving US 183
TxDOT hosted an open house Sept. 19 for residents to learn more about proposed improvements to US 183. These proposals include adding auxiliary, or merge, lanes between Metric Boulevard and Cameron Road. Other improvements would include adding a main lane on the southbound side and closing the entrance ramp near Georgian Drive.
Timeline: spring 2020-21
Cost: estimated at $3 million

3. Parmer Lane diverging diamond
Construction began in July at Parmer Lane and I-35 to add a diverging diamond interchange. Vehicles will cross over to the opposite side of the road to facilitate more efficient turning movements. Crews will add a southbound I-35 bypass lane at Parmer, and improvements at Parmer and North Lamar Boulevard are also planned. Utility work is ongoing.
Timeline: July 2019-mid-2021
Cost: $32.5 million
Funding source: TxDOT

4. RM 620 expansion
TxDOT is still weighing options to improve safety and traffic flow on RM 620 between the Mansfield Dam and US 183. Options include expanding to up to 10 lanes with elevated lanes. The department released its feasibility study in February 2017 and has been refining the study to focus on projects north of the dam. In early 2020, the agency will host an open house, wrap up the refinement and begin the environmental process.
Timeline: TBD on construction
Cost: TBD
Funding source: TBD

5. I-35 work
The I-35 project includes adding three flyovers between I-35 and US 183 as well as fixing the existing northbound I-35 to northbound US 183 flyover. In late September, crews installed concrete beams for the turnaround at St. Johns Avenue, which is expected to open in early 2020. In early November, crews will install beams for the southbound I-35 to southbound US 183 flyover.
Timeline: January 2018-mid-2021
