Using 3-D rendering, Boulder planners are offering the first real glimpse of a year-long, $7.4 million construction project on Broadway at Euclid Avenue that promises to test the patience of drivers this summer.

The city's transportation department this week posted a computer-animated video on YouTube that shows an artist's conception of the busy intersection with a planned underpass and pedestrian bridge linking the University of Colorado campus on the east with the University Hill neighborhood to the west.

"It has really helped to show what the future improvements will be there," said Noreen Walsh, a senior transportation planner for the city.

The rendering includes computer-generated models of stairways on either side of Broadway, an improved transit station along Broadway and a pedestrian plaza in front of the University Memorial Center.

Construction on the project is set to begin this spring, although a firm start date has not been set.

The project will likely require two of Broadway's four lanes to be closed at a time, leaving open one lane of travel in both directions.

The majority of the work that impacts traffic is scheduled to happen during the summer months, just after CU students leave for summer break in mid-May, according to Walsh.

The video is based on design concepts for the project.

While Boulder plans to chip in about $920,000 of taxpayer dollars for the underpass, the Federal Highway Administration will pay $3.9 million, CU will contribute $1.6 million, Boulder County will provide $500,000, the Regional Transportation District will put in $570,000 and the Colorado Department of Transportation will pay $400,000.
