Mill and Overlay projects are one component of the city's comprehensive pavement management program. Pavement surfaces tend to wear out much faster than the other components of a street (such as curbs, sidewalks, and utilities) due to the impacts of heavy vehicles. If a pavement surface is not maintained adequately, the pavement will need much more significant and costly repairs in a short amount of time to avoid deterioration of the roadway surface.

A mill and overlay consists of removing the top layer of pavement, usually 1 to 2," and replacing with new pavement. This process usually happens in 5 steps as follows:
You can drive on the new pavement once it is finished being rolled, which usually takes about a half hour or so from the time the paver puts the fresh pavement on the road. Flaggers will be directing traffic when you are prohibited from driving on the new pavement, please keep your eyes open for them.
Generally, you will be able to get in and out of your driveway at all times except for the following times:
Unfortunately, mill and overlay projects only address the surface of the pavement. If a pavement has cracks which extend down further than the top 1 to 2 inches of the pavement surface, those cracks tend to show up again after the new pavement is put down. These cracks are called "reflective" cracks and are common after mill and overlay projects. When these cracks appear, we will seal up the cracks so that they do not keep growing and ruin the new pavement.
Theoretically yes, but sometimes it is not a good idea to mill and overlay a street. When a street starts showing "alligator" cracking (lots of cracking in the street that looks like alligator scales), that pavement surface is usually too far gone for a mill and overlay to be effective. Also, all of those "alligator" cracks will come back through to the top of the pavement surface after the project is done, and then the mill and overlay project will have been a waste of money. At that point, a Full Depth Reclamation project is probably a better solution for that street.Sometimes a mill and overlay project is a bigger investment than is necessary to preserve the pavement surface. In those cases, a Chip Seal may be a better choice to preserve the pavement surface at a lower cost.
Parking will be limited at times during a mill and overlay project so that the contractor can complete the work effectively. "No Parking" signs will be posted at least 48 hours in advance of when parking restrictions will go into effect. When the parking restrictions are in effect, vehicles still parked in the construction area may be subjected to ticketing and/or towing. We will try to contact the vehicle owner(s) if we find any vehicles still parked on the street during parking restrictions.Parking restrictions may be posted for the following work:
Mill and overlay projects in the City of Red Wing are usually paid for using dedicated street maintenance funding from city property taxes. For certain higher-volume streets, State Aid funding from the State of Minnesota is used to supplement the regular maintenance funding.The City of Red Wing currently does not assess for Mill and Overlay or other pavement surface maintenance projects.
The city generally has a Mill and Overlay project of varying size and scope each year. Typically, city staff meets in the fall of each year to review pavement management data and budget information and take "field trips" to look at each candidate street. The city usually only plans these projects a year in advance, but sometimes with bigger Mill and Overlay projects the city will plan 2 years or more in the future in order to secure the needed funding to complete the projects.
