A major traffic tie-up on Lagimodiere Boulevard caused headaches Thursday afternoon.

The afternoon rush hour snarled after a semi-truck clipped a rail underpass and lost its load.

It was hauling another truck, which landed on its side.

The incident happened just north of Maginot Street.

Police blocked one northbound and one southbound lane as crews and a tow truck cleared the scene. 

No one was hurt.
