It's been a week and a half of smooth-sailing on the W-X, but Caltrans is still fixing 50.

We are heading into the second half of construction work on Highway 50, with lane closures moving to the westbound side of the roadway.

The three inside lanes of the W-X between 18th and 24th streets will be blocked off starting at 9 p.m tonight.

One lane of the northbound Highway 99 connector will also be closed, and we'll see a total shutdown of the ramp from Westbound Business 80.

Caltrans says delays could be longer than what we saw with eastbound work because of the complicated merge and a larger volume of commuters from Folsom, Rancho Cordova and El Dorado Hills.
