  • Length 11.71 miles
  • From Route 15 (the Merritt Parkway) in Trumbull
  • To Route 34 in Monroe

Route 111 starts at the Merritt Parkway, at the site of the state's only single-point urban interchange (SPUI). This was originally a cloverleaf interchange for Route 25; Route 111 follows the old Route 25 until it intersects the end of the 25 freeway in northern Trumbull.

At Route 25, Route 111 widens to four lanes, then narrows again after Purdy Hill Road in Monroe.

The old Route 25 south of the Merritt Parkway is state-maintained, but designated secret route SR 731 instead of Route 11.

Until the SPUI interchange was built at Route 15 in 2004, signs on the Merritt Parkway read Main Street, not Route 111: a "stealth" junction. New signs installed there do mention Route 111.

CT 111 History

In the 1920s, State Highway 111 followed today's Route 66 between today's Route 10 (Milldale) and Route 2 (Marlborough). In 1930, it was even co-signed with the old New England Interstate Route 3 to Waterbury.

The modern Route 111, commissioned in 1932, extended 7.75 miles from Route 25 in Trumbull (intersection of Main Street and Monroe Turnpike) to Route 34. Main Street south of this intersection was part of Route 25.

When the 25 freeway opened on June 1, 1982, Route 111 was extended south along former Route 25 to end at Route 15.

Further widening in Monroe

A reconstruction of Route 111 in Monroe was proposed, to increase safety and capacity without radically changing its character. Probably minor widening is planned. The project is in the 1995 Greater Bridgeport and Valley Transportation Improvement Program (TIP), slated for a 2007-2015 time frame. In April 2003, Congressman Christopher Shays requested $10 million in federal funds toward this project.

The state had developed a widening plan in the mid-1990s, addressing a 2.29-mile segment from Purdy Hill Rd. to Fan Hill Rd. Many residents opposed the plan, fearing it would detract from the town's rural charm.

As of mid-2005, a new plan was proposed:

Estimated cost was $10 million. In August 2005, Congressman Christopher Shays secured $1.2 million in federal funding for the work. Residents and officials seem happier with the compromise plan.

CT 111 Quotes

"REP. SHEA: Can I just respond to that since I was on the positive end of things. I will tell you that I'm also in a district that dealt with exactly what you said. We have Route 111. The State wanted to come in and widen it and all the plans were in motion and the townspeople came out and said no, we don't want you to do that. So that was the end of the improvement of Route 111."
