MoDOT starts construction on Natural Bridge safety improvements

ST. LOUIS – Drivers who use Route 115 (Natural Bridge) in the city of St. Louis regularly need to be alert as construction begins on a safety improvement project next week.

Starting Wednesday, August 5, crews will close the center turn lane and one lane in each direction on Natural Bridge between Salisbury/Parnell and Glasgow to construct medians in the roadway.  Work will run Monday through Saturday between 6 a.m. and 7 p.m.. Work will begin at Salisbury/Parnell and move west to Glasgow as crews complete work.

As part of the 15-month project, crews will be making several safety improvements along the corridor, including:

  • Reducing lanes between Shreve and Salisbury/Parnell. Crews will reduce Natural Bridge from two lanes in each direction to one lane in each direction, and will construct a median between the two lanes.  Drivers will have left turn lanes at cross streets.
  • Constructing roundabouts at Goodfellow, Vandeventer and the Salisbury and Parnell intersection.
  • Adding mid-block crosswalks with rapid flashing beacons and additional crosswalk lighting in several areas along the corridor.
  • Installing yellow reflective back plates around signals on Natural Bridge
  • Including higher visibility crosswalk striping.

Work is expected to continue through fall 2021.
