Crews are set to replace more of the signs along Interstate 19 next week. Some of the new signs are already in place.
Arizona transportation workers say they're brighter, larger and easier to read. But, the new signs will still be in kilometers. It's part of a statewide effort that began earlier this year.
The project will require closing lanes and ramps on parts of I-19 next Wednesday through Friday nights.
Here is a list of areas that will be affected:
Wednesday, Jan. 2
Thursday, Jan. 3
Friday, Jan. 4
