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.
