ODOT crews were busy until 4am Monday making scheduled repairs to I-405 southbound in Portland.

The route between the Fremont Bridge and the Marquam Bridge carries 60,000 to 125,000 motorists each day.

It's in the midst of an $11.6 million upgrade that will extend over four weekends.

ODOT spokeswoman Christine Miles says the work's going well.

Christine Miles "We were able to meet all of our goals for this weekend. Our major goal was to get rid of the old concrete and lay some new asphalt."

Miles says some traffic was delayed, but the backups could have been much worse. Intermittent problems were reported with drivers stopping before the closure, unsure which way to go.

Miles advises for upcoming weekends that confused drivers keep driving, and pull off when possible to get re-oriented.

Next weekend's work involves replacing stripes on the south-bound lanes with permanent ones, and some electrical work on bridge lighting.

The 405 project is one of several in Oregon this summer benefiting from  federal stimulus cash. Thirty percent of the project's cost is covered by recent stimulus grants.
