One person is dead following a late morning collision on Highway 3 between Fort Macleod and Lethbridge.

According to members of the Lethbridge RCMP detachment, the crash occurred at approximately 10:45 a.m. near the hamlet of Monarch prompting the closure of the eastbound lanes of the highway.

The crash involved a bicycle travelling eastbound on the shoulder of the highway and an eastbound car.

Morotists were encouraged to avoid travel in the area until the highway reopened. Eastbound traffic experienced significant delays as RCMP members rerouted traffic away from the crash scene.

The eastbound lanes of the highway reopened at approximately 1:30 p.m. but westbound traffic was halted following a second collision involving two vehicles.

The identity of the deceased has not been released.

An investigation into the fatal crash is underway.

Monarch is situated approximately 20 kilometres west of Lethbridge.
