Toll authority adding a fourth lane on the inside of freeway.

Pretty simple affair, a straight shot +1 lane down the median. Frustrating that a project this simple requires years of community engagement and environmental studies, but it's good to see CTRMA being proactive. They stay on top of things in the metro.

Also for SH US 183, TxDOT has scheduled public meetings to launch the environmental process to upgrade the section in north Williamson county to a freeway, and the section in Burnet county to 4-lane divided.

I know that the TX 183A Toll Road extension will soon open to end just north of the CR 213/CR 258 intersection (with the last interchange being at TX 29). Are there any plans to further extend the TX 183A Toll Road further north from there?

It doesn't look like there is anything official on the books (aka a "US-183A Phase 4" project). Although their "Phase III" web site states traffic volumes in that area North of Austin will increase 183 percent by 2042. That sounds like a good justification for TX DOT to start acquiring several more miles of ROW.

Right now growth in the Austin metro (especially in Austin city limits) is hitting the pause button due to the housing price bubble appearing to have popped. Once the economy goes through a big correction it's likely growth in Austin will resume.

While growth inside Austin itself has stalled (temporarily) towns near Austin are still growing. I-14 gets built out to the West and more is done to upgrade US-281 it's easy to imagine Lampasas booming. It could happen anyway.

An update on the 183A extension

EDIT: Opening on April 9th (tomorrow)

I have a Stylebook issue. Calling it TX-183A might somehow imply it is part of SH 183. SOmeone Actually used the term SH-183 (without even the A after it.)  It is correctly annotated as 183A Toll  The FHWA notes it as US-183A.
Look at it here. https://www.fhwa.dot.gov/ipd/project_profiles/tx_us183a_phase_III.aspx

Someone wants to make it belong to the state when it doesn't. It is owned and operated by Central Texas Regional Mobility Authority an independent governmental agency based in Austin.  It relates to the state like a city, county, or fire protection district. While they work WITH TxDOT, they are NOT TxDOT.

ANd yes, while the  the regional mobility authorities are confusing, they work well inside of Texas.

Maybe it should have been designated US 183A. After all, it parallels US 183. Any TX 183A should have connected with existing TX 183 in the Dallas-Fort Worth area.

I assume that 183A is the route number for the (tolled) main lanes, while US 183 runs across the frontage roads?

Similar to US 290:

[Echostatic]

Yes, "Toll 183A" is the name of the mainlanes and US 183 is the frontage road. Same goes for "Toll 183" vs. US 183 on the segment between SH 71 and US 290. It's not really a route number at all, just a name.

Speaking of TX-183A, GSV posted last February some shots of TX-183A construction at the junction of TX-29.

WE weren't speaking of TX-183A it doesn't exist. We were talking about Toll 183A which is the mainlane tollway to the frontage road which is US-183A.

If you have to assign a "regular" (outside of Texas) name, call it US-183A

Originally, the toll road was planned to be built by TxDOT and be designated as US 183A.  The planned designation was dropped when the project was transferred to the mobility authority.  183A is the name of the road, like "Dallas North Tollway."  It's written mostly with numbers, but it's still a name and not a numerical designation.

I think that the official name is "183A Turnpike."  I found that hidden in some documents that are public but get no interest.  "183A Toll Road" is more commonly used.

US 183 does not follow the frontage road, except south of Avery Ranch Blvd.  Most of the route through the area is along a parallel road to the west of the turnpike.  Late last year, the commission designated US 183 along frontage roads are far north as FM 1431, and then west to the existing road.  When those frontage roads are built, US 183 will be on the frontage road for a little less than half the length of the turnpike.  The existing route south of there will become BU 183Q (to add more alphanumeric fun).
