MONTEREY PARK, Calif. — Authorities Thursday announced some roadway closures beginning Friday and continuing through the weekend involving the San Bernardino (10) Freeway near the Long Beach (710) Freeway in the Monterey Park area.

"The closure will allow crews to safely conduct median barrier work," Caltrans said in a statement.

The work will begin Friday at 8 p.m. and continue through Monday at 6 a.m., at various times affecting the HOV lane of the eastbound 10 Freeway between the 710 Freeway and Atlantic Boulevard.

Also affected will be connector roads from the northbound and southbound 710 to the eastbound 10, along with the Alameda Busway onramp.

The ongoing $15.2 million project will upgrade the concrete barrier height to meet current standard design standards at 23 locations along 10 Freeway between the San Gabriel River (605) Freeway and the 710.

Closures are weather-permitting and subject to change.
