The ramps had been closed for an extended period to allow the construction of a new roadway for the northbound lanes. This will be the first section of the new roadway opened to traffic. The switchover will begin at about 8 p.m. and should be completed early Wednesday morning. On Thursday, the Ankeny Hill Interchange should reopen.
All activities are weather-dependent.
Rain or sub-freezing temperatures could delay these operations. ODOT urges motorists traveling in the area to use extra caution in the workzone.
