Illinois’ two U.S. Senators are looking into the safety of Lake Shore Drive. That follows last week’s blizzard, which forced hundreds of drivers to abandon their vehicles there.

Senators Dick Durbin and Mark Kirk are trying to coordinate efforts between different government agencies. At the top of the list is studying the impact waves could have had on Lake Shore Drive during last week’s blizzard if water levels hadn’t been incredibly low.

In a letter sent to the Army Corp of Engineers and the U.S. Department of Transportation, Durbin and Kirk said they want to talk about increasing the amount of green space along the lakefront in addition to preventing floods. They said the City of Chicago and the Park District will head up discussions on the local level.

Hundreds of drivers were stranded for hours during the storm after three accidents occurred in the same area in quick succession. Because of the standstill, Lake Shore Drive was closed to drivers for more than 30 hours.
