Art on wheels will again roll through downtown Lawrence during the annual Art Tougeau parade at noon Saturday.

The event, which takes its name from a play on “art nouveau,” celebrates self-expression via all things wheeled.

This year’s Pre-Parade Painting Block Party will be 5 p.m. to 9 p.m. Friday in the 900 block of New Hampshire Street, during Final Fridays. Participants can bring cars, bikes, skateboards or anything else on wheels to decorate for the parade.

On parade day, vehicles will line up at the Lawrence Arts Center, 940 N.H., then will head south on New Hampshire, west on 11th Street, north on Massachusetts Street, east on Seventh Street, south on New Hampshire, and west on 10th Street to Replay Lounge, 946 Mass.

Organizers will announce awards about 1:30 p.m. then kick off the post-parade Wheel-apalooza block party (think music, food and, of course, things on wheels) on 10th Street, next to Replay.

Event planners say awards — created by students at Lawrence schools — will go to vehicle entries that did an especially good job, folks showing noticeable creativity and inventiveness.
