All lanes along the stretch of highway known as the W-X have re-opened. 

For nearly two months, commuters dealt with construction along what was referred to as the Fix 50 zone. 

The second phase of the project, which began June 6, finished up today -- six days ahead of schedule. 

Last night at about 9 p.m., crews began to move traffic back to normal -- removing cones and re-striping the lanes. 

Caltrans estimated the transition would be complete by about 8 a.m. this morning, but like we're used to, traffic was back to normal early, with commuters zooming along Highway 50 by about 6 a.m.

Non-traffic interfering night and weekend work will continue throughout the year. This work includes occasional lane closures for permanent striping, continued seismic retrofitting of the columns underneath the viaduct, and lighting and fencing installation in the parking lots beneath the project area.

Final completion is expected in December 2014.
