Commissioned in 1932; no big changes since then. It is a bit shorter today because US 5 was relocated at East Windsor Hill in the early 1940s.

In 1996, the state proposed widening Route 194; one of the alternatives was even a four-lane boulevard. However, no widening has been done. In 1998, the intersection at Ayers and Graham road was improved for safety reasons.

Across US 5 from Route 194 is Ferry Lane, leading to the landing of the former Bissell's Ferry (and across the Connecticut River, Bissell's Ferry Road in Windsor). This was the oldest ferry (1648) in the United States, but is no longer operating. The nation's oldest continuously operating ferry (except in winter, because of ice) is on Route 160.

Extend Route 194 south along Buckland Road to I-84 in Manchester. The idea is not original; in 1995, local officials requested adding Buckland Road to the state highway system. It was widened to four lanes at about the same time.
