Weather permitting, the ramp from Wright Brothers Blvd. to I-380 Southbound will be closed for up to two months, beginning the morning of Tuesday, July 7. During this closure, construction crews will be working on building a new ramp. This will be one of the last steps to finalize the new Diverging Diamond Interchange (DDI), which is anticipated to open later this year.

During the closure, traffic will be routed south on 6th St. SW/Hwy 965 to F12 (120th St. NW). Temporary traffic signals will be added at the intersection of 6th St./Hwy 965 and F12 (120th St.) to assist the detour traffic flow.
