St. Louis – Drivers who use I-270 and Dunn Road near New Halls Ferry Road should be aware of a permanent ramp closure and road redesign beginning Tuesday, November 16.
Starting at 7 a.m. Tuesday, November 16, crews will permanently close the westbound I-270 exit ramp to New Halls Ferry Road. Additionally, the eastbound lane of Dunn Road from New Halls Ferry Road to Old Halls Ferry Road will close. Only westbound traffic on Dunn Road will remain open between Old Halls Ferry Road and New Halls Ferry Road. When complete, this portion of Dunn Road will be converted to a westbound one-way outer road.
Drivers planning to exit westbound I-270 to New Halls Ferry Road can use the new Old Halls Ferry Road exit and continue on Dunn Road to New Halls Ferry Road. Drivers traveling eastbound on Dunn Road will now use Pershall Road to travel from New Halls Ferry Road to Old Halls Ferry Road. All detours will be signed.
Animated detours will be posted on the I-270 North Project website at: http://www.i270north.org/map/. Travelers can also contact MoDOT’s customer service center at 1-314-275-1500 or the I-270 North Project Team at: I-270North@modot.mo.gov.
