It provides an alternate route to I-95 south of downtown, and connects it with the US 6 freeway west from Olneyville towards I-295 and Connecticut.

The final crossing, back into Providence, is just after the Cranston Street interchange, where Niantic Avenue ends.

Upon crossing into Providence Route 10 passes over and parallels the Northeast Corridor as well as interchanging with Huntington Avenue.

In the early 2020s, this current interchange was upgraded to conform to modern highway standards, most notably providing direct access from Route 10 North to US 6 West via a flyover ramp (Exit 3B).

Eastbound US 6 exited at Westminster Street to follow its old alignment towards downtown, but westbound US 6 was completely rerouted between downtown and Olneyville, following Kinsley Avenue, Eagle Street and Harris Avenue to reach the Olneyville Bypass.

One plan by the state designated the Huntington Expressway south of Olneyville as Interstate 184 (I-184), but this was rejected by the Federal Highway Administration.

[3] The first section of the Route 6-10 Connector, from the east end of the Olneyville Bypass to Dean Street, opened in 1972.

US 6 westbound was not moved in 1972, but left to continue to enter the Olneyville Bypass from Harris Avenue at that time.

A new ramp from Tobey Street to the bypass was added, however, replacing a removed left entrance from Broadway.

The other part of the Connector opened in 1988,[3] connecting the Huntington Expressway and Olneyville Bypass to Interstate 95 in downtown Providence.

[8] In 2020, RIDOT renumbered the exits as part of a statewide project to convert to mileage based numbering.
