JEFFERSONVILLE, Ind. (AP) — Motorists using Interstate 65 in southern Indiana will face what's being called a "Big Squeeze" beginning next week.

The Ohio River Bridges Project said Monday it expects major congestion and delays beginning Sept. 2 while it reduces three lanes in both directions to two for nearly 1½ miles from the Kennedy Bridge northward.

The lane closures reducing traffic capacity by one-third are projected to continue until late 2016. Both directions of I-65 will be squeezed into the area where the southbound lanes are now to build new permanent northbound lanes to connect with the new Ohio River bridge under construction.

The Ohio River Bridges Projects suggests motorists adjust travel plans to avoid peak times and consider alternate routes, including the Sherman Minton Bridge connecting New Albany and Louisville, Kentucky.
