Two Projects Moving Forward on 4th Street!

November 29, 2011 at 9:35 am | Posted in Bike News, Get Involved | 6 Comments

The 4th Street Bicycle Blvd. will be another step closer to reality as two mini-roundabouts are projected for installation on 4th Street by the summer of 2012. One will be located at 4th Street and Norton, the other will be at 4th Street and New Hampshire. Recent meetings with the Windsor Square Homeowner’s Association and the Wilshire Center Koreatown Neighborhood Council resulted in support for the mini-roundabouts. LACBC is reaching out to the community through additional local organizations in an effort to further build support for the roundabouts and 4th Street as a whole. We’ve  had a roundabout at 4th and New Hampshire in mind for a long time and LADOT chose the two locations because they are the intersections of “Bicycle Friendly Streets” in the LA Bike Plan. Each mini-roundabout will benefit two “Bicycle Friendly Streets” since 4th, Norton, and New Hampshire are all designated BFSs.

Mini-roundabouts will improve the safety of everyone passing through the two intersections. They will slow motor vehicle traffic, reduce the potential for collisions, and will enable people on bicycles to maintain forward momentum since the roundabouts will be 4-way yield instead of 4-way stop. You can read more about mini-roundabouts thanks to a recent blog post by Richard Risemberg here, and there’s additional information on the FHWA website here.

The 4th Street Bicycle Blvd. campaign calls for multiple improvements on 4th Street and the roundabouts are two steps in the right direction. We’re working to build additional support for the roundabouts to help ensure implementation and that the roundabouts include attractive, appropriate landscaping.

There’s plenty more to do on 4th Street to make it a neighborhood greenway that will benefit people on bicycles, people who walk, and people who live in the area. If you’d like to get involved, please contact Colin Bogart at

  1. Love IT! Here is a conceptual rendering I did last year of a roundabout at this intersection:

  2. Nice, but…I’d say the roundabout in the rendering is not quite wide enough, unless combined with curb bulbouts. Your more arrogant drivers will take great joy in swerving round it at speed, since the deviation it imposes appears to be pretty small.

    Remember, if people were nice, you wouldn’t need traffic control devices at all.

    It’s our whacked-out human psychology. Cars are private space, so people in them feel that they really do “own” the road they squat over, though that road is public space. That’s why they see all others as “intruders.”

    Physical traffic control devices–such as narrow lanes, roundabouts, etc.–serve to induce civil behavior without reference to civil sentiments. (Signs work only when back up by cops.) But a too-small roundabout will simply be a challenge to a motorist, not a restraint.

  6. we really need a round about on highland and 4th, or put a crosswalk at the least
