OMAHA, Neb. (AP) — The Nebraska Department of Transportation has shut down several interstate ramps in east Omaha expected to affect 47,000 drivers and cause traffic headaches for motorist in Omaha and western Iowa.

Station KETV reports that westbound Interstate 80 ramp to northbound Interstate 480 has been closed along with northbound Highway 75 ramps to westbound I-80 and northbound I-480. Also, the F Street entrance ramp to northbound Highway 75 is closed.

Drivers are being rerouted east on I-80 to northbound I-29 in Council Bluffs, Iowa, then westbound back into Omaha on I-480. The ramps were closed Wednesday night for construction that’s expected to last until the first week of October. The DOT says the closures are needed for bridge repairs and repaving.
