LOS ANGELES — Over 2,600 miles from where they hope to clinch their record 18th banner, the Celtics are already impacting traffic back in Boston.

The Red Sox announced Tuesday the Boston Transportation Department will close various streets in the Fenway neighborhood and surrounding areas during tonight’s Celtics playoff game here at the Staples Center.

Brookline Avenue will be closed to vehicular traffic from the Landmark Center to Kenmore Square beginning at the end of the third quarter of tonight’s Celtics game. The area around Fenway Park has been posted with no parking/tow zone signs.

Starting at 7:30 p.m., the Boston Transportation Department will begin towing vehicles parked on Ipswich Street, from Boylston Street to Charlesgate, and on Brookline Avenue, from Park Drive to Kenmore Square.

This will also be the case on Thursday if there is a Game 7 between the Celtics and Lakers that evening in Los Angeles. The Red Sox urge fans to use public transportation if at all possible.
