A two-vehicle wreck on northbound State Route 1 at the Route 273 interchange created quite the mess for morning commuters and environmental cleanup crews on Tuesday, June 5, 2018.

Delaware State Police say the accident unfolded at 3:15 a.m. when a car, driven by an 18-year old Port Deposit, Maryland woman, crashed when the driver tried to avoid hitting a deer.

Troopers say a dump truck then slammed into the car which was facing the wrong way.

The truck driver reported not seeing the car because its headlights had become disabled due to the first crash.

As a result of the accident, police said the dump truck overturned, spilling a load of petroleum coke all over the roadway.

Neither of the drivers sustained serious injuries.

The wreck started a chain reaction of road closures and jammed highways as commuters attempted to find alternate routes, some of which became nearly gridlocked at times.

At approximately 6:45 a.m., highway officials elected to close the highway at Tybouts Corner, where SR-1 and U.S. Route 13 split at a jughandle interchange.

Delays at that point had stretched all the way to the William V. Roth Bridge over the Chesapeake and Delaware Canal and eventually reached to the Scott Run Connector.

It wasn't until 10:25 a.m., seven hours after the original crash, that the roadway was fully opened.

At least one driver reported to WDEL a commute that lasted two hours.
