By now, you've likely noticed a drop in speed limit from 55 to 45 mph in certain areas along the I-440 corridor, as well as coned off shoulders near the Hillsboro Pike and 21st Avenue ramps. Prepare to see more lane closures as TDOT wraps up a few things — such as lighting work near Hillsboro, noise wall construction and other projects — before heavier construction begins in February.

Curious about what you'll see while driving on I-440 this year? Look back at the interactive timeline below to see what's going to happen, when it's going to happen and how you can prepare for your daily commute.

See the map below to find closures that might affect your daily commute.
