Year 3 of the Bonanza Drive roadwork starts on Monday.

Drivers should not be as displeased as they might have been during the first two years, though.

Matt Cassel, the Park City engineer, said the work crews last week prepped for the start. People driving on Bonanza Drive likely saw the crews start to mobilize, with heavy machinery arriving at the site. The workers also put up the orange and white traffic markers on the road.

The city engineer said the crews will begin excavating early in the week in anticipation of installing retaining walls and ramps on either side of the pedestrian-bicyclist tunnel that was put in but not opened last year.

There has not been any work at the site of the tunnel since November. Officials did not want the crews working during the busy holidays-Sundance Film Festival period. Blueprints based on the soil conditions at the site also were finalized in that time, Cassel said.

Drivers should not encounter the closed roads and traffic backups of the last two years, though, the city engineer said. He said no work is planned within the roadway, but lane shifts marked with traffic cones might be required.

“We will not close any lanes . . . Bonanza should flow through all of this,” Cassel said.

He anticipates dump trucks, concrete trucks and trucks delivering materials to the site will be pulling in and out of the Bonanza Drive-Iron Horse Drive intersection, though.

The work will not require intersection closures or closings of driveways serving businesses, Cassel said.

The work should be completed by the middle of April, if there are not delays caused by the weather, the city engineer said. He wants the pedestrian-bicyclist tunnel to debut at about the same time.

City Hall had wanted the tunnel opened last November, but setbacks based on the soil conditions delayed the opening.

Some of the other work planned on Bonanza Drive in the upcoming weeks includes:

  • installing several small stretches of sidewalk alongside Bonanza Drive
  • putting in streetlights
  • building decorative fencing close to the Bonanza Drive-Rail Trail intersection designed to protect pedestrians and bicyclists
  • installing guardrails on the ramps in and out of the tunnel

    In July, Cassel said, more work is planned, with landscaping scheduled to be planted and road markings slated to be put down on Bonanza Drive. Concrete in hues of color will also be put in close to intersections.

    The Bonanza Drive roadwork started in 2009 as a two-year project. The crews, though, were not able to finish the work in 2010, requiring this year’s schedule.

    Businesses along Bonanza Drive especially suffered during the 2010 phase, which put the workers along the street’s business corridor.
