ALBEMARLE COUNTY, Va. (CBS19 NEWS) -- Construction has been ongoing for months on the diverging diamond interchange at Richmond Road and Interstate 64.

It briefly shifts traffic to the opposite side of the road and gets rid of left turns crossing lanes of oncoming traffic.

"It will make the commute for people coming in and out of Charlottesville through that interchange, it should improve that experience because we should gain significant efficiency of vehicles moving through that interchange," said Lou Hatter, the communications manager for the Virginia Department of Transportation.

Zion Crossroads has the same type of interchange.

VDOT is finishing up the work on this Albemarle County interchange this weekend, so traffic patterns are changing.

On Saturday night through Sunday morning, traffic will be detoured onto I-64, get off one exit later and then having to make a U-turn.

By 5 a.m Sunday, one lane will be open under the bridge.

Hatter says to expect congestion and gave some tips for getting used to the pattern.

"Slow down, watch for signs, there will be plenty of directional signage," he said. "If you follow the pavement markings and directional signs, you'll be fine. The speed limit through the work zone and through the project is 25 miles an hour."

The main work for the project will be completed by the time the Monday morning commute comes around. At that point, everyone should be getting in and out smoothly and efficiently.

There will still be overnight lane closures until February.
