Roads and Highways That Are Now Parking Lots

Parts of old Oregon 50/US-26 are now the parking lot for Mt. Hood Skibowl and Trillium Sno Park.

Parts of former US 40, now MD 144 that was downgraded from 4 lanes to 2:

The Schuylkill Expressway

It's probably a stretch, but it looks like Maryvale Drive in Cheektowaga NY was once part of the Kensington Expressway before it was extended east.

It doesn't look like a parking lot to me.  It's just a dead end street.

Parts of the old alignment of Meridian Street around Pratt Avenue here in Huntsville are now parking lots.

The Lucy Hill Naturbahn Luge Run crosses part of a former alignment of M-35 in Negaunee. Part of the rest of the alignment is used as parking on the property.

(The style of luge seen in the Winter Olympics and other international competitions is called kunstbahn and uses artificial refrigeration to form the ice surface in banked curves, while naturbahn uses natural ice frozen on a flat surface.)

A lot of old bridges in Florida are changed to fishing piers when a replacement is built.  The old road is often part of the parking lot

Part of old VA 110, which I forgot about until I drove past the Pentagon this morning. The old route came close enough to the Pentagon to make it vulnerable to a truck bomb. A truck ban was the interim fix right after 9/11, with police patrols at exits to that stretch of the highway, and anti-tank guns pointing into traffic to stop any trucks that slipped past the patrols -- certainly made my evening commute home interesting The long-term fix was to move VA 110 about 400 feet farther away from the Pentagon, at which point the truck ban was lifted. That took out some of the Pentagon's outer parking, but in exchange the old highway was used to create more close-in parking spaces.

Also, some streets once open to the public between E Street N.W. and the White House were closed off, and converted to parking for White House staff. That might've happened pre-9/11 -- some Federal agencies have long used security as an excuse to try (not always successfully) to convert public parking into their own private parking spaces.

Indeed, perfect examples being the old over water approaches of the original Sunshine Skyway bridges (Interstate 275 and US 19).
