All lanes of northbound Highway 101 in Palo Alto reopened early Tuesday after Caltrans crews completed emergency roadway repairs, according to officials.

The two right lanes of northbound Highway 101, just north of the Embarcadero Road interchange, were closed Monday after the lanes began to loosen and unravel, creating deep grooves and potholes in the road, Caltrans said.

The closure began about 3:30 p.m. Monday before being lifted at roughly 12:45 a.m. Tuesday.

Caltrans workers applied a patching material in an effort to reopen the lanes, according to the transportation agency.
