Driving a Split Merge

Traffic on I-275 from Northline Road to 5 Mile Road during road work in 2021 through 2023 will be maintained using what is called a split merge, where one direction of traffic will use a local lane and an express lane, with the local lane used for ramp access only.

The video and graphic below shows an example of a split merge during road work on the southbound I-275 median lane and shoulder. In this scenario, two northbound lanes (blue cars) stay on the northbound side while southbound traffic (green cars) is split between the northbound and the southbound side in a local and express lane.

In a split merge, traffic wanting to get on or off the freeway would want to use
the local lane while through-traffic would use the express lane.
