For the next two months, crews will rebuild the ramps and change how drivers enter eastbound I-270.  During the closures, signed detours will direct motorists from eastbound I-270 to exit at Washington Street/Elizabeth Avenue and continue traveling eastbound on Pershall Road to West Florissant Avenue.

Crews will be making repairs to the bridge barrier.  The left lane of eastbound Route N to eastbound Route 364 will also close during this work.  All lanes should reopen by 9 p.m Saturday, August 27.
