AASHTO wants to completely pave over Maryland for more cars and less of everything else

…
AASHTO argues that because America’s population growth over the following decades will be concentrated in urban areas, state DOTs need to help more and more city dwellers get around. Their prescription? 30,000 more lane-miles of urban interstate. That’s an increase of more than 40 percent over the 85,000 urban lane-miles that already exist. AASHTO also wants to build another 40,000 lane-miles to the non-interstate federal highways in urban areas. If Robert Moses were alive today, he’d probably arrive at the same policy response.
As Liu writes at MTR, more highways are not the answer to America’s urban transportation needs.
If all AASHTO’s projected growth in VMT were matched with new road capacity, you’d have to add 9,641 square miles of new lanes: an area the size of Maryland. That’s not even including the space needed for parking spaces or shoulders. And it doesn’t account for induced demand: Before long, those new highway lanes will just attract new drivers, as momentarily less-congested roads lead more people to organize their lives around car commuting, canceling out any congestion benefits new road capacity might offer.

[B’ Spokes: Let’s talk density, one lane mile of urban interstate can hold 20 cars at a time (when working optimally,) one bus can hold 60 people. One mile of interstate = $40 million, one bus = $0.4 million. The denser the development the denser the mode of travel needs to be as well improved economics. We are not in Kansas any more and trying to accommodate low density travel for lots and lots of people in one small area is plain and simple not a physical reality.]

In addition, every dollar spent on road expansion comes at the expense of repairs. According to a new study by U.S. PIRG, 63 percent of major urban roadways were in less than good condition.
