I might catch some flack for this but... here I go.
The new plan makes this project not worth even pursuing.
Here are the stated goals of the project:
1.) Improve safety: Crash rates on FM 1774 and SH 105 exceed the statewide average
2.) Address traffic growth: Since 1980, traffic has increased 274 percent on FM 1774 and 197 percent on SH 105
3.) Improve regional connections: Provide transportation system continuity to surrounding area
4.) Address evacuation needs: Increase evacuation capacity during emergencies
Here's how the revised project addresses them:
1.) Now that this project will not be grade separated, it will add a light onto SH150 and include additional crossing. Maybe you reduce the crash rates at FM1774, but overall crashes will increase.
2.) SH150 traffic will increase after this project. FM1774 traffic will increase for those taking 249 to Montgomery / Lake Conroe.
3.) Improve regional connections. IDK what that even means. They're building in the middle of nowhwere a two lane road w/ no passing lane. Its a county rd essentially.
4.) A two lane road as an evacuation route? ROTFL. You're kidding, right?
Here are the ways you actually fix each issue without the square peg (new highway / road) for a round hole (see 1-4 goals of project).
1.) Grade separate or upgrade SH105 and FM1774 intersection
2.) Put in more lanes on each road then.
3.) Again, IDK what this means. The county / regional planning should address connectivity problems w/ their mobility plans. A rural / suburban expressway to Houston does little to address Grimes county mobility issues IMO.
4.) This is already being done w/ the 290 expansion really. In addition, upgrading FM1774 and SH105 will also accomplish the same thing.
IF this was done as a grade separated tollway, then a lot of the stated goals would be addressed. Maybe not the best way but, the project now doesn't address any. It provides no immediate benefit with only the faint hope that in the future a real highway is built. This is terrible, terrible waste and public policy. All Texans are paying for this w/ their tax $'s.
If you're pairing down your goals and a road must be built, the design needs to change. In addition, in 2000 when this was thought up, there was no new bullet train going in or plans for I14. All of this has to be taken in consideration.
So what should be done? Either kill this section (not happening as there's too much momentum) or re-route it. My thoughts? Use the utility / bullet train ROW & alignment or just go with the ROW along the slow railroad west of 1774 (BNSF line?) that drops you off between Stoneham and Plantersville. Future connections to I14 become easier as you just follow the train / utility ROW up to I14.
But I'm a lone voice. The real reason for any new road in / around Houston is more about opening up land for housing or commercial purposes. Mobility is just a nice bonus.
A two lane road along a railroad that has minimum crossings makes a hell of a lot more sense from a safety standard and evacuation standard.
