Southbound Arch at Galena Creek Bridge Begins to Take Shape

The falsework for the southbound arch of the Galena Creek Bridge is under construction and visible from US 395. Approximately half of the falsework is in place and the future arch span can already be seen by local residents and passing motorists.

Once complete, there will be two (2) arches, each supporting the southbound and northbound bridge decks respectively. The Galena Creek bridge will measure 1700 in length with an arch span of 690 feet. The bridge deck will stand 295 feet above the base of the creek.

Concrete pours for the arch are scheduled to begin the first week of August.

Galena Creek Fill Complete

The Galena Creek fill has been completed and is now being graded to create a stable work surface for crews and equipment. Bridge contractor, CC Myers, has begun drilling for the falsework foundation piles and will soon begin erecting falsework that will support the Galena Creek Bridge construction.

The fill measures 390 feet wide at its base, tapers to 200 feet wide at the top, and is approximately 120 feet high. 380,000 cubic yards of material were moved during the construction of the fill. A 44-foot diameter culvert runs through the base to preserve the natural course of Galena Creek and to provide enough additional capacity for potential increased flows during major storm events.
The fill is slated to be removed and the affected hillsides restored once the project is complete.

Work in Full Swing at South End of Project

Work is now in full swing at the south end of the I-580 Freeway Extension Project near the intersection of Bower's Mansion Road and US 395. Crews have removed some trees and have begun the removal and stockpiling of topsoil. The removal of noxious weeds is in progress and crews have started the construction of drainage pipes and culverts in the area. Much of this activity is visible from US 395.

Continued earthwork to support the roadway bed has begun south of Galena Creek between Browns Creek and Parker Ranch Road.

I-580 Public Tours Restricted

NDOT has announced it will restrict public tours for the I-580 Freeway Extension Project. The project tours were well received and typically booked months in advance during the tour season. However, with an eye toward fiscal responsibility as well as public safety, project officials decided that restricting the tours until work zone access is increased and made safer would be in the public's and workers' best interests.

"As the project moves into the next phases of construction, increased activity on the site will make it difficult to ensure that tour participants have a safe and enjoyable experience," says NDOT Project Manager, Todd Montgomery, P.E. "Also, in light of our State's current budget concerns, we feel that cutting costs in this non-essential area is a fiscally responsible and appropriate course of action."

Group and organizational tours may still be available on a limited basis subject to construction activity, weather conditions, and staff availability. Please contact the NDOT Public Information Office at 775-888-7000 for additional information.

NDOT will continue to update their project website and publish a project newsletter in an effort to keep the public informed on the project's progress.

Hours of Construction

NDOT is working hard to make progress on the Freeway Extension Project, with as little impact to area residents as possible. This includes keeping the project on schedule and moving forward as rapid as possible. The contractor is generally limited to working on the Galena Creek Bridge and near residential areas from 7:00am to 9:00pm Monday through Friday and, if the contractor chooses, 9:00am to 9:00pm on Saturday and Sunday. Few special situations, such as large pours of concrete, may require extended work hours. These situations will be individually approved by NDOT and noticed on the website well in advance. Additionally, residents within 3 miles (5km) will be noticed 2 weeks in advance of large concrete pours outside of the normal working hours. Project lane closures are also not permitted on state and national holidays, as well as during the local "Hot August Nights" and "Street Vibrations" events.
