Under consideration are three interlocal agreements with the county to fund improvements to two segments of CR 112 and an extension of Old Settlers Boulevard.
CR 112 is split into two segments—a stretch from FM 1460/A.W. Grimes Boulevard to CR 117, and CR 117 to CR 110—which will be widened from a two-lane road to a six-lane urban roadway.
Among other benefits, the CR 112 upgrades will provide access to a planned housing development called Avery Centre, which is proposed to bring 335 townhomes and 339 single-family homes to the area when completed.
Per the agreements, Williamson County would contribute a maximum of $7,993,500 for the FM 1460/A. W. Grimes Boulevard to CR 117 segment, and $9,496,000 for the CR 112/Avery Nelson Parkway from CR 117 to CR 110 segment. Williamson County documents stipulate the contributions may not exceed 50% of the total cost of the projects.
Round Rock officials have not specified a maximum funding amount for the three projects.
The third agreement is for an extension of Old Settlers Boulevard to CR 110 that will run through the back of the Siena subdivision via an existing right-of-way.
Williamson County could commit up to $7,772,000 toward the project, also not to exceed 50% of total costs.
City Council awarded a $934,919 contract to Aguirre & Fields LP to finalize the roadway in October 2021. Construction services are included in the contract if they are deemed necessary.
