It immediately crosses over I-95 and heads south towards the Morris Cove neighborhood, passing near Tweed-New Haven Airport and providing access to Lighthouse Point Park.

After crossing Morris Creek into the Momauguin section of the town of East Haven, it becomes South End Road then turns east along Silver Sands Road after 0.2 miles (0.32 km).

[1] The road serving Morris Cove and the Annex neighborhoods of New Haven were town-maintained until the beginning of 1963, where the changes mandated by the 1962 Route Reclassification Act took place.

In 1969, Route 142 was truncated to its original western terminus and the former alignment was redesignated as SR 704.

In 1997, the eastern end was reconfigured to use Coe Avenue instead of continuing on Silver Sands Road.
