The Milford Parkway begins at U.S. Route 1 in Milford at a trumpet interchange. It meets Interstate 95 shortly after, and heads north towards Connecticut Route 15. At exit 3A, the parkway shrinks to two lanes, and has a partial interchange to Wheelers Farms Road by way of Wellington Road, which is also served by exit 55A on the Wilbur Cross Parkway. After the interchange, the Milford Parkway merges with southbound Route 15.
On ConnDOT highway maps, the route is referred to as the "Daniel S. Wasson Milford Police Department Connector."[3]
At its completion on September 2, 1940, the Merritt Parkway ended at the present-day Sikorsky Bridge crossing over the Housatonic River, and the Wilbur Cross Parkway was planned to continue in the northeast direction towards Hartford. The Milford Parkway was then built as a connection between the two parkways and U.S. Route 1 (US 1). The Milford Parkway was opened to traffic on September 2, 1942[citation needed].
The long loop ramp connecting to southbound Route 15, including the interchange with Wheelers Farms Road, was completed in 1993.[citation needed] Until this point, there was no access to the Milford Parkway from southbound Wilbur Cross Parkway.[4]
On June 23, 2003, the parkway was renamed to honor of Daniel S. Wasson, the first police officer to die in the line of duty in the city of Milford.[2] Wasson was killed on April 12, 1987, when he was shot by a motorist he had pulled over.[2]
Prior to 2012, the parkway was treated mostly as a ramp, signed as "To I-95 / US 1" on Route 15 and Wheelers Farms Road, as well as "To Route 15" on both I-95 and US 1. In summer 2012, exit numbers were applied to the parkway's four interchanges. Also included in the project were the first signs to designate the parkway by the Milford Parkway name, located on US 1. However, entrance signs at the other three interchanges still do not list the name of the road.
