Expected traffic impacts week of March 21
Range Line Street remains down to one lane in each direction until approximately March 30 while the contractor builds the new eastbound I-70 bridge and retaining walls at Range Line.
The left southbound lane is closed from south of Vandiver Drive to south of the eastbound I-70 off-ramp. The right northbound lane will be closed from south of the eastbound I-70 on-ramp to the westbound I-70 off-ramp.
As a result, there is no access to northbound Range Line from eastbound I-70. All other ramp movements are open.
A diagram showing the traffic flow is available on the project website - www.modot.org/ColumbiaBridges.
Project completion: 45%
This project is nearing the halfway mark! Here’s a general look at work still to come:
March 28 - Eastbound Business Loop between the entrance to the Comfort Suites and the existing roundabout will close at 7 a.m. on Monday, March 28. The westbound lane from the roundabout to the west will remain open. Traffic traveling east between Stadium Boulevard to the roundabout will need to go west to Stadium and then use I-70 or city streets to travel east. This closure will last several weeks.
March 28 and 29 – Both southbound lanes of Range Line from the westbound I-70 on-ramp to the eastbound I-70 off-ramp will be closed from 6:30 p.m. to 5 a.m. on Monday, March 28 and Tuesday, March 29 to set girders on the new eastbound bridge over Range Line. Traffic will be routed to westbound I-70 to Providence.
March 30 – All lanes of Range Line will be open, with only periodic lane closures moving forward. The access from eastbound I-70 to northbound Range Line will re-open. However, there will no longer be a dedicated left turn from southbound Range Line to eastbound I-70 due to the placement of the new bridge supports. Instead, the inside lane will be a shared straight and left-turn lane.
Early April – Eastbound I-70 traffic will be shifted to the new I-70 bridge at Garth.
Early May - Eastbound I-70 traffic will be shifted to the new I-70 bridge at Range Line.
Mid-May – The new bridges at Garth and Range Line will be slid into place, and the old bridges will be demolished.
Early June – Business Loop at I-70 will be closed for 45 days.
