Earlier:

Witnesses say that northbound traffic on the Disraeli Freeway is extremely backed up Wednesday morning.

A semi-trailer is hung up on the curb of the exit from Talbot Ave. onto northbound Henderson Highway.

The semi is not only blocking the Talbot exit but all lanes of northbound traffic.

Callers say that traffic on northbound Disraeli is at a standstill as traffic diverts onto eastbound Talbot.

At this time there is no estimate on how long until the semi can be moved.
