Here’s how the condo collapse in Surfside is affecting traffic in the area

Drivers who usually take Collins Avenue and Harding Avenue in Miami Beach near the 79th Street Causeway or the Broad Causeway should use alternate routes after Thursday morning’s building collapse in Surfside.

A section of A1A that connects Miami Beach to Haulover and Sunny Isles Beach has been shut down. There is no information yet on when it will reopen.

The collapse is at 8777 Collins Ave., the Champlain Towers South Condominium. Here’s what you should know:

Detours and alternate routes

▪ Southbound Collins Avenue traffic is being sent west at 96th Street, where Bal Harbour turns into Surfside and southbound Collins turns into one-way Harding Avenue. That means more traffic piling up on Kane Concourse in Bay Harbor Islands and the Broad Causeway, which ends at Northeast 123rd Street in North Miami on the mainland.

▪ An alternate route: Head up to Northeast 163rd Street to reach the mainland.

▪ On northbound Collins Avenue, traffic is pointed west at 86th Street. That means a backup on Collins and Harding Avenue. That traffic joins the usual shuffle of cars heading down to 71st Street, where many turn for the 79th Street Causeway toward Miami, or shuffling all the way down to Interstate 195 (the Julia Tuttle Causeway).

▪ As an alternate route, if you’re on the mainland, stay there and use Biscayne Boulevard. If you’re coming out of Miami Beach and heading north, consider taking the Tuttle over to the mainland and heading north before cutting back over on the Broad Causeway.

▪ The newest street closures come on Collins Avenue from 85th to 92nd streets and Harding Avenue from 85th to 90th streets. There is no word yet on when roads will reopen.
