Highways 20/49 through Grass Valley will be subject to overnight closures next week, from 7 p.m. to 7 a.m. Sept. 10-11, as work nears completion on the Dorsey Drive Interchange project.

Traffic will be detoured from Brunswick Road to Idaho Maryland Road along Nevada City Highway, although Sutton Way will also be open.

This closure will allow construction crews to repave Highway 20/49 between those exits in preparation for the project’s planned completion next month. Crews are also finishing the grading for the on- and off-ramps for the Dorsey Interchange in both directions, and sometime in the next week crews will placing aggregate base materials in preparation for subsequent paving.



On Monday traffic control will be in effect on Dorsey Drive between Pampas Drive and Spree Avenue from 7 a.m. to 4 p.m.

“They’re going to do a polyester overlay on the bridge deck to provide good rideability,” said Trisha Tillotson, an engineer with Grass Valley’s Department of Public Works. “It smooths out the bridge.”




This will involve pouring the material and spreading it out, but Tillotson has said that most observers won’t notice the difference visually.

The Dorsey Drive Interchange Project is nearing its completion, and officials say that it is currently on time and on budget.

So far, however, officials say it’s too soon to provide a precise date of completion for a project that’s been the works for several decades.

“After this next week, we’ll have a better idea of exactly when we’re going to complete the project,” Tillotson said. “Right now, though, it is looking like mid-October.”
