Adding Up What Urban Highways Really Cost
A new report maps the economic toll that downtown freeways exact on 142 US cities β and tallies up what that land could be worth if it was developed for other uses.
A new report by @thedotcity.bsky.social quantifies the economic toll of downtown freeways, and the economic potential of tearing them down.
The 66K acres that downtown freeways occupy could yield more than half a trillion dollars of development and over $5b annually in property taxes.

For sure β I just think it's notable they're emphasizing it here on this map, which they haven't done before.
It's an interesting reflection of the agency's focus, and I think reflective of the realities of a slower line overall.

The "express service" depicted on the map seems to me to indicate a certain number of trains would skip all the Central Valley cities.
This was probably always going to happen, but with slower track express service will be a more important part of the business plan.

This is just one service scenario; there would still be local service to the Central Valley, just a question of how much.
As for the broader strategic pivot, it's a matter of whether state laws can be changed and the project can attract private investment. It's not official until that happens.

The little Merced spur has been a big question mark for CAHSR lately. Interesting to see it still on this map.
Previously, the agency was planning a major transfer station to local trains at Merced, but now it looks like Madera will be the transfer point.

This "express service" concept (see stations outlined in red) seems to be a way to speed travel times despite slower design speeds.
It's ironic that, in order to make the business plan work, CAHSR will have to skip over the Central Valley cities it spent so much to reach.

The new CA High-Speed Rail business plan calls for using existing tracks in the LA area, similar to the shared Caltrain tracks in NorCal.
This concept would cost $126b and could be in service by 2040, the agency projects.
No indication yet of the updated travel time estimates.

The 12,000-home project Trump and Mamdani discussed could well be Sunnyside Yard in Queens.
It's a proposal in the works since 2014 to build 12K affordable homes on top of the Amtrak railyard, a sort of progressive answer to Hudson Yards.

How malls can become the midtowns of the future
Mall and office park redevelopments are a generational opportunity to create new nodes of urbanity.
The midtown model of urban development β mixing homes, offices, stores and civic institutions within a walkable radius β is as old as cities themselves. The mall/ office park model was a half-century aberration.

Because it would have had to travel over the mountains, going up a steep grade and navigating some curvy sections. It wouldn't be possible to average 70mph in that kind of geography. Plus, the route was longer and more circuitous.

Architectural beauty is a really important issue in housing advocacy, but it can be hard to address with policy.
So many "design" regulations end up making buildings uglier.
This piece is a great summary of the kinds of policies that could actually promote beautiful buildings.

Wow, I'm impressed. Bloomberg has the best article on the Sepulveda Line I've seen. No errors, very detailed, pushed back on nimby talking points, centered voices like Matute, Schneider, and Raman, and even mentions an EIFD! Full marks.

LA is planning what could be the most expensive and complex transit project in American history β a subway across the Sepulveda Pass.
If it ever gets built, the benefits would be huge. An 80 min trip shaved to 20 mins, 100K+ rides per day, transfers to 4 other lines.
