It’s literally already 4 lanes under the first 429 overpass heading north and they’re currently widening it to 4 lanes at the 2nd overpass…
If you mean the Turnpike, that has a published plan already as well on the county website (I’ll maybe find it later when I actually post this after work). The space is there for narrow or divided 4 lanes all the way up to Colonial, with the possible exception of the area around Stoney Brook West Country Club and that big landscaping business. It’s so easy to see the space for widening on Google Maps for most major roads if you actually want to see it, and it’s even more obvious (IMO) when driving to notice the space.
It is a case of NIMBYism because I can guarantee you that if the road and other infrastructure concerns were fixed and running at an A LOS 24/7 with school capacity to spare, a lot would find yet more issues with the project. At the community meeting someone asked if there would be buses and when they answered no I heard several people around me say “good, we don’t want those either.” They might get backed into the corner of “home values” and “those people” as the only remaining options, but there’s a not insignificant amount of them. I was both surprised and unsurprised at the 180 in tone between the community meeting and the BCC meeting from those opposing it. Yes, some would say “okay, my concerns are taken care of, make it happen,” but I would put money on it not being a majority.
A mass transit bus system that's not Lynx will be essential for those living in the proposed development. Otherwise, those without a car will be using ride sharing services or taxis.
