TX DOT goofed around for over 20 years doing nothing with the US-380 corridor between Denton and McKinney when it was clear to everyone that highway would have to be converted into a freeway at some point in the future. Now TX DOT and everyone else involved is looking at a lot of painful choices. Growth in the Northern reaches of the DFW metroplex shows no signs of slowing. New arrivals from the West Coast and Northeast US keep arriving all the time. So many people are arriving that the scope of that future US-380 freeway corridor needs to be expanded from just Denton-McKinney to a larger Decatur-Denton-McKinney-Greenville project.
TX DOT used to be really good at securing the ROW of future freeway corridors, typically building divided surface streets with huge medians. That policy created a hard-line physical barrier against any developer hijinks and other wavering political BS.
US-380 needs to be upgraded to an Interstate class freeway on as much of the existing ROW as possible. I think segments B, E and C for the proposed McKinney bypass is an acceptable solution. The US-380 main line through the middle of McKinney is just too overrun with development. A long elevated freeway is the only thing that could possibly work there. The four corners of the US-380/US-75 interchange are totally blocked in with development, making it impossible to build a directional interchange there without removing at least a couple dozen businesses.
Also, I think the McKinney bypass is far enough South from the Colin County Outer Loop that they would not be redundant. Further, TX DOT needs to get on the stick about US-82 between Gainesville and Sherman.
All very good points. As stated before, have no "dog in this fight" but am of opinion you need to fix what you have, and not create a curvy inefficient alignment through developing residential areas. Decision making, planning, and design standards have dropped since the beginning of the Rick Perry administration, have seen it personally, up close, in El Paso County. Despite infusion of vast sums of money.
A good friend of mine, recently re-located from Wisconsin to the Whitesboro TX area. West of Sherman. Was able to purchase 5 +/- acres of land for a very good price, far cheaper than in most parts of Wisconsin. Already has a house and a shop up. Am guessing Property taxes there are better than the oppressive levels of El Paso County in far W Texas.
Probably that US - 82 corridor is becoming like US - 380 W of I-35 W, lined with "ranchettes" and semi rural horse properties.
