The most interesting sections of Route 68 are in Wallingford: after passing under Route 15, the Wilbur Cross Parkway, it overpasses US 5 (with a small connector road in place of an interchange), then widens into a 2.5-mile stretch of four-lane partially controlled access highway leading to Interstate 91.

Two historical proposals never came to fruition: a freeway from I-91 to Route 68, and a two-lane extension from Durham to Killingworth.

CT 68 History

Commissioned in 1932 from the old State Highway 325, Route 68 originally existed only between Route 63 in Naugatuck and Route 70 in Cheshire. Two unsigned state roads, SR 730 (Church St) and SR 607 (Barnes Rd) continued through Wallingford to Durham.

Extension to Durham, and I-91

In 1964, possibly to give Yalesville and Durham better access to the planned I-91, Route 68 was extended over SR 730 and SR 607 to Route 17 in Durham. Signing changes appear to have taken place in 1966, when I-91 opened here.

The "Super 4" segment in Wallingford

In 1973 and 1974, Route 68 was relocated in Wallingford, leading to the 2.5-mile segment of four-lane, undivided, access controlled road (almost a Super 4). Several parts of the former Route 68 exist as Barnes Road, which the new highway parallels. The state labeled these parts as SR 752A in 1973, and turned them over to the city in 1974.

Other changes

In Cheshire, Route 68 was straightened out west of where it crosses Broad Brook Reservoir in 1966. The original route followed a sharp curve north, closer to the shore.

Another realignment was done in Wallingford in 1968, but I have no details for it.

In 2002, a one-mile segment from Williams Road to Leigus Road was widened (mostly four lanes with turning lanes), and two side streets were made into cul-de-sacs to decrease the number of access points. This widening was first suggested in a 1988 study of Route 68 between Durham and Cheshire.

In 2004, the interchange with I-91 was slightly realigned, with the overpass widened to five lanes, to add left-turn lanes onto the entrance ramps. This was supposed to finish in fall 2003, but a structural problem, requiring redesign and reordering of bridge supports, delayed its completion.

Proposed freeway

The state once had grander plans for Route 68: a freeway, leading from a proposed Route 10 freeway in Cheshire across Wallingford into Durham. This was in the category of "proposed highways for future traffic needs", and was never constructed. In fact, I haven't seen evidence of any public hearings or detailed design for the Route 68 freeway itself.

Proposed Extension to Haddam

In 1935, the state assigned Route 180 to a proposed trunk line route from Durham to Haddam. The 1938 official state map shows the proposed route. Route 180 was never built; if it had been, it would be a natural extension of Route 68.

Proposed widening declined

In 1998, though congestion and a commercial boom in Wallingford had touched off calls to widen Route 68 near US 5, the state said it would not be widened in that area.

CT 68 Quotes

"There are still drivers who can remember when there was no such animal as Route 68 stretching its snaky way from Durham to Union City. If that constituted a "route" 30 or 40 years ago, no one knew it. But over the intervening years, thanks to I-91, Route 8, and the increasing mobility of our population, the scarcity of east-west routes has been noted and eased by piecemeal improvements to what is now 68."
