Big headaches are expected for thousands of commuters who use Hwy. 100 in St. Louis Park. So AAA Minneapolis is offering a free forum on the project.

At 6:30 p.m. Wednesday at AAA's offices at 5400 Auto Club Way (off Hwy. 100 and Excelsior Blvd.) officials from the Minnesota Department of Transportation will give an overview of the $60 million project that will reduce the highway to two lanes in each direction from April through October.

The forum is the first of three or four that AAA will host this year, said Garrison McMurtrey, a AAA spokesman. With the project to affect more than 136,000 drivers, "we thought Hwy. 100 would be a good start," he said.

Participants should register by Friday by e-mailing foundation@aaaminneapolis.com.
