Commuters in Carbon County should be gearing up for some gridlock on the Pennsylvania Turnpike Monday morning.

Turnpike officials say the southbound tube of the Lehigh Tunnel will be closed between 8 a.m. and 2 p.m., both Monday and Tuesday.

That means there will be two-way traffic on the northbound side of the tunnel.

Officials are warning commuters to be prepared for the new traffic patterns.
