Beginning late Wednesday night, all traffic on SB 270 approaching Dorsett will be moved onto a temporary bridge over Dorsett. This temporary bridge will be used while southbound and then northbound 270 bridges are rebuilt over Dorsett. Speed limit is reduced to 45 mph, the lanes are a foot narrower than usual, and there are no shoulders on this temporary bridge. Work will continue 24/7 for the next 60 days.
This initial phase which begins Wdnesday night will affect SB 270 at Dorsett. Suggested alternates are Lindbergh to Page or the Earth City-Maryland Heights Expressway to the Page Avenue Extension.
