The Project

This project will replace the 1,295-foot long northbound section of the Providence Viaduct Bridge which carries I-95 over numerous local roads and highway ramps, Amtrak's Northeast Corridor and the Woonasquatucket River. This section of I-95 carries more than 220,000 vehicles per day. It is the busiest section of I-95 in Rhode Island and one of the most heavily trafficked highway bridges on the East Coast.

Construction of the Viaduct Northbound is thanks in large part to the efforts of Rhode Island's Congressional delegation, which secured a $60.3 million federal INFRA grant for the project. Our project includes the construction of a new collector-distributor (C-D) road along the right side of the Interstate. This eliminates the weaving conflicts and congestion that plague the segment of I-95 Northbound from the 6/10 Connector and Downtown on-ramps to the Route 146/State Offices interchange.

We also will reconfigure ramps to disentangle conflicting movements, improving motorist safety and comfort, and reducing congestion and delay. The new ramp system will provide more efficient connections among I-95, the 6/10 Connector, and Route 146. This new configuration will vastly improve the crippling congestion caused by traffic trying to access I-95 northbound from the 6/10 Connector and by traffic trying to exit I-95 to access Route 146 or the state offices.

An earlier design for Providence Viaduct Northbound called for reusing the bridge during construction but the winning proposal by Skanska/Manafort presented a solution that saved a year of time and approximately $1 million.

Other Project Highlights

We are not only replacing the Viaduct, but will rebuild 11 bridges in total, many of which are of critical safety concern and will correct the inefficiencies, congestion and safety issues that exist today. Among them:

  • Replacement of the Smith Street Bridge
  • Replacement of the Route 146 Bridge over I-95
  • Building new retaining walls alongside I-95 and Park Street
  • Rebuilding the Atwells Avenue on-ramp to I-95 North
  • Rebuilding the ramp from the Route 6/10 Connector to I-95 North
  • Rebuilding the ramp from Memorial Boulevard to I-95 North


Ongoing overnight bridge work at the I-95 North Viaduct requires the closure of Exit 37A, B and C off I-95 North, and the Atwells Avenue on-ramp to I-95 North, Sunday-Thursday nights from 11 p.m. to 6 a.m. On Tuesday, from 7 a.m. to 3 p.m., we’ll have a lane shift on West Exchange Street, from Fox Place to Sabin Street, to place the new I-95 North Viaduct Bridge deck above it.
