Disneyland's Main Street U.S.A. became a bit of a maze for visitors starting last week when workers began construction on the main thoroughfare into the theme park.

Crews are working on the concrete along Main Street U.S.A., mostly at night, for almost two months, said David Gill, a Disneyland Resort spokesman. On Friday, visitors could see construction walls starting at Town Square near the park's entrance down to Sleeping Beauty Castle.

Disney does work on Main Street on an as-needed basis, usually every three to five years, Gill said. Crews last did a similar project in January 2009.

During this year's project, Main Street Vehicles, including the omnibus and streetcars, are banned from the street. The vehicles are expected to return in early March, Gill said.

Previously, Disney reported that the vehicles would come back Feb. 16, but they are now scheduled to resume operation later.

The parade also is on hiatus during construction.

The last regular-season parade, Celebrate, ended in November. It was followed by A Christmas Fantasy parade, which ran over the holiday season. Disney is now preparing for a new procession, Mickey's Soundsational Parade, which is set to begin later this spring.
