Is night work planned for the Grand Avenue bridge project?

Yes.

Night work is not a preferred shift for construction projects, primarily because of the lack of adequate lighting and the safety concerns of workers. However, the challenges of this large and complex project will require occasional work at night to minimize traffic delays and provide safe, adequate working space for the construction activities taking place. Working at night also helps to minimize traffic impacts for work that could affect peak travel times (morning and evening rush hours).

You will see the first night work in about a month to move the existing pedestrian bridge to its temporary storage location near 14th Street and Coach Miller Drive. This will require removing the pedestrian bridge in sections and using a very large semi-trailer to take each section down Grand Avenue to the storage area. Because of the dimensions of the loaded semi-trailer, night work and lane closures will be required to ensure safe passage. We will probably need to remove the traffic signals downtown as well to allow adequate vertical clearance.

Night work will also be necessary for “overhead” work throughout the project. For example, installing the temporary pedestrian walkway will require crane operations that would not be as safe or productive during the day.

Night work is also being planned throughout the detour phase of the project from August through December 2017.
