I-285, Ga. 400 both affected by flooding during Monday afternoon storms

Two of metro Atlanta’s most-traveled roads were heavily affected Monday afternoon by severe storms, leaving drivers stuck in floodwaters.

Between 3 and 5 p.m., both Ga. 400 South and I-285 West were shut down following separate instances of flooding, according to the WSB 24-hour Traffic Center. The shutdowns, which did not last more than an hour in either case, caused lengthy delays on the Northside to kick off Monday’s evening commute.

The first route to close was Ga. 400 after muddy water pooled along the southbound lanes near I-285 about 3 p.m., the Traffic Center reported. The water’s unappealing brown hue came from the nearby construction related to the I-285/Ga. 400 interchange project, which is expected to be completed next year.

By 3:45 p.m., all lanes had reopened, but travel remained slow in the area.

However, the area became gridlocked again after floodwater seeped onto I-285 West near Ashford-Dunwoody Road about 4 p.m., according to the Traffic Center.

Lanes began to reopen within the hour, but the interstate did not fully reopen until a little after 5 p.m.

Inches of rain fell in both DeKalb and Fulton counties during the storms, prompting the National Weather Service to issue a flash flood warning for the counties, along with Gwinnett, until 10:45 p.m. Monday.
