541:(RIDOT) estimated that this vehicle volume would exceed 25,000 by 2005. This high vehicle capacity would be dangerous because of Route 403's sharp curves and low speed limit in Davisville. The narrow route through a densely populated region was particularly unsuitable for the high volume of commercial trucks that used it to access Route 4 from the Quonset Business Park and container port. RIDOT began studies on improving the route in 1987, exploring both the widening of the existing route to a four-lane, undivided highway and the construction of a freeway as options. The proposal to widen the existing road was ultimately dropped, as it would less effective at relieving congestion in the region and would require significant demolition of existing structures in Davisville. A freeway alternative to be constructed north of the existing route with more direct access to Route 4 and an eastward expansion beyond US 1 into the Quonset Business Park was selected instead.

Phase 2. The freeway and ramps from Route 403 west to Route 4 north and from Route 4 south to Route 403 east opened on
October 23, 2008. The route was posted with a speed limit of 50 miles per hour (80 km/h). The final portion of Phase 2, ramps from Route 403 west to Route 4 south and from Route 4 north to Route 403 east, opened in December 2008. As part of the construction of a trumpet interchange with Route 4 in East Greenwich, a new northbound Exit 7 on Route 4 was completed; the original Route 403 was accessible only from Route 4 southbound. All major construction on the freeway was completed in December 2008, one year ahead of schedule; minor projects continued on the relocated route until early 2009.

Westbound Route 403 has no direct interchange with either US 1 or Davisville Road; the route's first westbound exit in Quonset is signed as "To US 1," and connects to Post Road via Gate Road, a commercial outlet in Quonset.

Davisville Road in Davisville. During Phase 1's construction, traffic was maintained on the existing Route 403 (Devil's Foot Road); the only major alteration to the route was the setting of a new eastern terminus of the road at US 1, as the previous terminus was demolished to allow for the

From 2006 until 2008, while Phase 2 of the relocated Route 403 was constructed, traffic on the newly completed freeway from
