Traffic Advisory: 210 Freeway overnight closures to impact drivers through Saturday.

A major construction project on the 210 Freeway is underway, and it will impact drivers in several cities. The overnight closures started Monday night and will last through Saturday, according to Caltrans officials.

Parts of the freeway in Pasadena, La Crescenta and La Canada Flintridge will be closed for Caltrans' 210 Pavement Rehabilitation Project.

People living and working near the freeway were told by Caltrans officials to expect noise, vibrations and dust associated with the work, though water trucks will be used to minimize dust and noise levels are not expected to exceed state and federal regulations.

As part of the project, the westbound Angeles Crest Highway (Loop) on- ramp and westbound Ocean View Boulevard off-ramp will be closed through the month of August.

The following restrictions are planned from 7 p.m. to 6 a.m. nightly through Saturday on the 210 East:

Also from 7 p.m. to 6 a.m., the northbound 2 Freeway ramp to the eastbound 210 will be closed, along with the eastbound 134 Freeway connector to the westbound 210.

The northbound 2 Freeway connector to the westbound 210 Freeway will be closed from 11 p.m. to 7 a.m.

On the northbound 710 Freeway, the Del Mar Boulevard on-ramp will be closed from 9 p.m. to 7 a.m., while the California Boulevard on-ramp will be closed from 11 p.m. to 5 a.m.
