As a series of dangerous speed maneuvers and street takeovers continue on the new 6th Street Viaduct Bridge in downtown Los Angeles, speed bumps are being installed and Los Angeles Police Chief Michel Moore is urging the public to remain vigilant to help an already overwhelmed police force. 

Tuesday night LAPD shut down the bridge again in an effort to prevent crime. The closure will last "until further notice" due to illegal activity, LAPD tweeted. 

Speed bumps are being installed as city officials hope to mitigate the crimes. A center median and fencing to discourage people from scaling the archways could also be installed soon on a temporary basis, according to Moore.

The bridge opened July 10 and connects Boyle Heights and the downtown Arts District, CBS Los Angeles reports.
