The regional transportation authority is getting into the spirit for one of Vancouver's biggest community celebrations.

TransLink has unveiled a pink articulated bus, which will be part of this year's Pride parade.

The event begins at noon on Sunday (August 4) on Robson and Thurlow streets.

The bus will also show up on some routes served by articulated transit vehicles.

In addition, TransLink has promised to increase service on the Millennium and Expo lines on Sunday.

That's not all. A shuttle will run from Waterfront Station to the parade viewing area to make things easier for people with mobility issues.

"The Vancouver Pride Society is thrilled that TransLink will be shining its brightest colours at this year's Pride parade and has a more fully integrated partnership with VPS," society executive director Andrea Arnot said in a news release.

Some bus routes will change over the weekend

Due to festivities downtown and in the West End, TransLink will adjust service on the following routes:

* 5 Robson/Downtown from 11a.m. to the end of service on Friday (August 2) and from 6 a.m. until the end of service on Sunday;
