Correction: Commenter Steven White correctly points out that there are indeed already two on-street bike corrals in the Downtown Arts District. So this isn't the first downtown L.A. corral - it's the third, and, AFAWK, it's the first downtown L.A. corral west of Alameda Street.
L.A.'s Department of Transportation (LADOT) has installed a new bike corral, the first in downtown Los Angeles. It's on the east side of Main Street, just north of 5th Street, right in front of Peddler's Creamery, where the main attraction is yummy "bicycle-churned ice cream." And there's more - in addition to the bike parking there's a fix-it stand with pump and all. According to LADOT Bike Program Instagram, Councilmember Jose Huizar will be there will be at an official opening celebration ceremony today at 4 p.m. If today's Metro committee meetings end early enough, Streetsblog L.A. will be there to enjoy a scoop or three.
If you want a bike corral in front of your business, follow the instructions found on LADOT People St.
