The ramp from westbound Montgomery to southbound I-25 closes tonight… forever. As part of the upgrade to I-25, this ramp is being eliminated. You will need to make a left turn onto the frontage road. Once the big project is done in a couple of years, the new bridge will have two left turn lanes to get on I-25 southbound.
Get all the info on the project here. And you can sign up to get text messages about changes in traffic flow and also they will text you when there are accidents in the construction zone.
There is also a story about this change from KRQE News 13.
