In 2018 SH 199 has freeway sections mixed in with non-freeway sections. A three-mile section between Lake Worth and Azle was upgraded to freeway standards and opened in 2018. In 2020 work began on the Lake Worth bridge. There are long-term plans to upgrade all of the corridor west of I-820 to a freeway, but no schedule for completing the remaining section to IH 635 as of 2018.
