Heat and humidity might not be the only things that make drivers hot this weekend. Another 15-mile shutdown of Interstate 35W through Minneapolis and Roseville just might, too.

MnDOT plans to finish resurfacing the stretch between County Road C and NE. 4th Street that it began last weekend, and work south of downtown includes the demolition of the 40th Street pedestrian bridge. The bridge will not reopen until 2020, largely becausenew bridge piers cannot be built until several stages of temporary traffic lanes on I-35W are completed below the bridge, said MnDOT spokesman Kevin Walker.

But as the 40th Street bridge shuts down, MnDOT was to have opened the rebuilt 38th Street bridge Friday night. That bridge has been closed since early March.

Not far away, the Uptown Art Fair takes over streets near Lake Street and Hennepin Avenue Saturday and Sunday, while the Powderhorn Art Fair will draw traffic to south Minneapolis. On the sports scene, the Loons play at 7 p.m. Saturday at TCF Bank Stadium and there are Twins games Saturday and Sunday at Target Field.
