On June 1, 2025, the Texas Highway Designation Files page will be removed and replaced with this one.  It's the same function with a different layout.  When you enter search terms, it shows the results on the same page.  You must click a button to see the information.  If you enter "State Highway" and "200" it will have one option, but you must still use the button to see the file.  If you enter "200" it gives you three files, FM, SH, and SS.  You must click one to see its file.  You will not be able to link directly to a file, but if you enter enough information to get to a single road, then there will be only one button available.

It does still show a list of highways for a category, a function I find useful.  However, it can list only 1,000 entries.  This is enough for every category other than FM roads.  Thousands of those are left off.  The second highest number in a single category is state highway loops, with 349.

It can't handle letters, so to find the OSR and NASA files, you have to search for state highways generally and scroll to the bottom of the list.

Despite this fact, I do still like the new look.

This might warrant its own thread, here's a video (in a slightly informal style), showing the planned SH 6 expansion through Bryan and College Station.

11 miles of SH 6 will be expanded to six lanes, almost all interchanges will be reconstructed, including a DDI.

Question for DFW area. TX Spur 366 crosses the 2011 Margaret Hunt Hill Bridge. The bridge was built with two stub ramps on the east end. Riverfront Blvd. ramps were forced to the inside of Spur 366 while the stubs are on the outside. What were these intended to serve?

Those would've connected to the cancelled (or practically cancelled?) Trinity Parkway (project overview).

The clearest plan view I can find for that is in this PDF from the Wayback machine (schematic roll 3 from this NTTA page). There's a different take on the connection in this older I-35E plan.

Elm is correct about the stub ramps. The Trinity Parkway is officially canceled. It was removed from the official regional plan years ago. The idea of of a small road inside the levees to provide access to proposed parks inside the levees has also faded away. In fact, the parks inside the levees also appear to be canceled, replaced by parks outside the levees.

There's a new proposed highway in San Antonio called the South Texas Parkway.

At this rate, quit to step into fictionnal roads territory, I suggest to extend the South Texas Parkway from I-37 to I-10.

How would building this "South Texas Parkway" compare to widening two-lane segments of TX Loop 1604 to four lanes?

I guess this parkway being located between I-410 and Loop-1604 will probably play a role similar to the Wurzbach parkway.

Does the area have a lot of traffic demand? The area around the Wurzbach Parkway seems a lot busier and more densely developed, while this south side still seems relatively rural.

I'm not from the area, though, so I am curious.

I guess there was some recent growth in that area and it was bigger than they anticipated and seems they want to be prepared from more growth.

TxDOT is currently renumbering the exits along I-27 between Amarillo and Lubbock... going up from the 100s to 500-600 mile range to account for the future southern extension of I-27 south of Lubbock.

Speaking of which, TxDOT had a ribbon-cutting ceremony back in April on extending I-27 4.2 miles south of its former terminus at 82nd Street in Lubbock... 

[Stephane Dumas]

If I'm correct, I-27 is extended down to 130th street/FM-1585 which is where Loop-88 is constructed.

I feel like this is definitely a premature move... I can understand being  set on extending I-27 down to I-20, but anything south of there is a little more in the air. Anything south of I-10 is a pipe dream.

Not to mention, do they have an exact alignment planned out they're basing these numbers on?

Wikipedia's Interstate 27 page has been updated to show a few of the new exit numbers at the northern end of the existing Interstate 27 corridor: https://en.wikipedia.org/wiki/Interstate_27#Exit_list. Google Maps shows Interstate 27 continuing to the northbound off-ramp/southbound on-ramp to the FM 1585/130th St. interchange (although Street View images from August 2023 SB and June 2024 NB show only US 87 signage south of 82nd St.). If there is one thing is for certain, Interstate 27 will be a very long Interstate Highway in the future (although none of us will likely live to see it completed to Laredo, if it ever makes it that far).

I plotted out a route on Google Maps from I-27's current northern terminus in Amarillo to the southern terminus of I-35 in Laredo, passing through Lamesa, Sterling City, San Angelo, Del Rio, Eagle Pass, and Carrizo Springs (the routing that I've seen suggested on the AARoads wiki and other places) and came up with 650 miles, which is pretty close to the 653-mile route implied by the exit numbers.
