The eastbound half of the road construction project on I-80 in Sacramento will switch lanes this coming Saturday, July 19.
Dennis Keaton with Caltrans says the open lanes will switch. Traffic will use the left two lanes as "through lanes" with the right lane dedicated to offramps.
"The new right lane is the only way you will be able to access the exits. So, for about a 7-to-10 mile stretch, in order to be able take Northgate, Truxel or any of those ramps, you're going to have to stay in the right lane, or else you're just going to go through the project area on those two far left lanes."
Keaton says on the westbound side, the three right-hands lanes will remain open as crews work to repair problems.
"They're still working on basically the interior side. They're having to redo some unsound concrete that was originally put down and it had to be done over because it didn't pass inspections."
Keaton says Caltrans is investigating who is it fault for the bad concrete.
When it's finished, the "Across the Top" project will have repaved 10 miles of highway and added a bus and carpool lane.
The project is scheduled to be completed by 2016.
