Night work

Nighttime construction

Nighttime construction or maintenance is any construction/maintenance activity occurring between 8:30 p.m. and 7 a.m. and within 500 feet of hospitals, senior living complexes, private residences, apartment buildings, businesses and hotels/motels. 

Construction or maintenance activities that are generally prohibited during 8:30 p.m. and 7 a.m. include pile driving/removal, concrete pavement demolition, pavement sawing, concrete crushing operations and jack-hammering. However, there will be times when noise producing operations will have to occur at night because of the need for pavement to cure or be sawed, or lanes closures that allow access to the work area.

Why?

Why work at night?

While MnDOT recognizes nighttime road construction is an inconvenience for people who live or work near the construction zone, it is sometimes unavoidable due to traffic volumes and in some cases it substantially saves time and money. Doing nighttime construction minimizes disruption to motorists and pedestrians - less traffic congestion; increases motorist and worker safety – often fewer motorists on the road; and is more efficient as the work is uninterrupted.

Why not work at night?

The cost of nighttime construction is generally higher than similar daytime construction activities. Some additional expenses associated with nighttime construction include paying overtime and higher wages for construction workers and additional traffic and lighting control costs.
