The Route 6/10 Reconstruction Design-Build Project is currently 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 truck of the interchange each day with two thirds of those trips originating or destined for points outside of Providence.
The Route 6/10 interchange has fallen 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 also 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 in the western section of Providence. Due to steady growth in automobile traffic and increase reliance on heavy trucking for freight, many elements of the interchange soon 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 on infrastructure in critical condition in order to meet safety and load requirements for the facility to remain in service. RIDOT recently completed a $5-million repair contract for work on these bridges, which consisted of repairs to the temporary shoring and bracing erected several years ago as a "bandage" to the problem.
The Route 6/10 Interchange Reconstruction project would reconstruct the entire interchange within the existing highway ROW, while replacing or removing the seven structurally deficient bridges within the project study area the Project plan highlights include:
|Broadway Ramp Closure|
|Route 10 North Shift|
|Route 6 East Crossover|
|Westminster Street Traffic Pattern|
|Broadway Traffic Pattern|
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.
|Construct Temporary Route 10 NB|
|Construct Temporary Route 10 NB Off-ramp to Westminster Street|
|Construct temporary pavement along
median,for Route 10 SB
|Shift traffic along Route 10|
|Close Broadway off-ramp,
|Construct north side of Westminster
|Construct north side of Broadway Bridge|
