The Project

First Vehicles Drive on the New 6-10 Huntington Viaduct

The Route 6/10 Interchange Reconstruction project is reconstructing the entire interchange within the existing highway right of way, while replacing or removing the seven structurally deficient bridges within the project area. The project highlights include:

• The Huntington Viaduct (Route 10 southbound) will be removed and the roadway lowered to approximately the grade of Route 10 northbound and below the reconstructed bridges carrying Westminster Street and Broadway.
• A direct connection to provide the missing move from Route 10 northbound to Route 6 westbound by construction of a flyover ramp, improving regional traffic flow and reducing local traffic congestion in Olneyville.
• Replace the Tobey Street on-ramp with a new two-way connection between Tobey Street and Harris Avenue that will enhance access across the highway at this location. A new Harris Avenue connection to either Route 6 westbound or Route 10 southbound (including a new one way westerly service road) will address traffic weaving issues at the existing on-ramp.
• Construct new bridge crossings over the highway for Westminster Street, Broadway, and Harris Avenue/Tobey Street. These wider boulevards will include new, multi-use paths providing separate, safe routes for pedestrians and bicyclists. These new crossings combined with replacing the existing Huntington Viaduct with a depressed roadway will substantially reduce the existing highway barrier between the neighborhoods of Olneyville to the west and Federal Hill and West End to the east.
• New bicycle/pedestrian paths extending through the project area from Union Avenue to Tobey Street that will enhance connectivity between area neighborhoods and connect the Woonasquatucket River Bikeway and Washington Secondary Bike Path.
• Better local traffic circulation and improved access.
• Gateway aesthetics: Additional measures will be taken for landscaping and visual improvements

HISTORY OF THE ROUTE 6/10 PROJECT

The Route 6/10 Reconstruction Design-Build Project is the largest Design-Build Project in Rhode Island Department of Transportation (RIDOT) history. The 6/10 interchange is located just west of downtown Providence in an area of Providence known as Olneyville It serves as a critical east-west regional link for automobile and truck traffic between Interstates 295, 95 and 195. Nearly 100,000 trips are made through the interchange each day with two thirds of those trips originating or destined for points outside of Providence.

The Route 6/10 interchange fell into a state of disrepair with seven of its nine bridge structures rated structurally deficient. In addition to replacing the bridges and ramps of the interchange itself, this project will address existing bridges serving local streets that are integrated into the interchange due to their proximity and grades. All will be brought into a state of good repair. The project also includes construction of a "missing move" from Route 10 North to Route 6 West. The creation of this missing move will serve to reduce or eliminate through traffic from the streets of Olneyville, thereby improving pedestrian safety in the community.

The existing system of highways and ramps comprising the interchange was originally constructed in the 1950s as a bypass around Olneyville, which at the time was a distinct urban center. Due to steady growth in automobile traffic and increase reliance on heavy trucking for freight, many elements of the interchange failed to meet emerging highway safety and serviceability standards. The problem became worse as additional regional highway connections were made with Route 10 and Route 6 (former RI-195) in the 1960s and 1970s. Most all of the now functionally obsolete elements of the interchange (including insufficient merging lengths and curve radii, unusual and substandard on- and off-ramp configurations, and other deficiencies) persist to this day.

In recent years many of the structural elements of the interchange have fallen further into disrepair, requiring extensive shoring, bracing and other interim support measures in order to meet safety and load requirements for the facility to remain in service. Just prior to the start of construction, RIDOT had to spend $5-million in repairs to the temporary shoring and bracing erected several years ago as a bandage to the problem.

Commuter rail service is a great alternative for commuters from Warwick and South County who normally drive through the interchange. RIPTA bus service offers several options too for an easier commute.

Why We're Replacing the 6/10

• The 6/10 is old, built in the 1950s
• Links three major commuter roadways
• Way above capacity, carrying 100,000 vehicles daily
• Nine bridges, seven are structurally deficient
• Has been bandaged and propped up for years
• Millions of dollars spent to keep the bridges open and safe
• We have to do this work - it cannot wait any longer
