The I-95 Providence Viaduct Northbound:

  • ✓ Broad economic impact is realized from reduced crashes and time savings
  • ✓ Yields immediate and sustained improvement to mobility, safety, and quality of life…now and in the future
  • ✓ The 50 year old bridge and roadway are in dire need of replacement and geometric improvements to efficiently handle today’s demands
  • ✓ Benefits to a substantial portion of the traveling public clearly justify the investment
  • ✓ Substantially improves connections between people and centers of employment, education, and services
  • ✓ Air quality improvement is achieved through reduced vehicle emissions

The northbound viaduct involves the following key elements:

  • New Collector-Distributor Roadway – A collector-distributor (CD) road will be constructed along the new northbound viaduct to eliminate a major weave caused by entering traffic from Route 6/10 and downtown Providence that competes for limited gaps on I-95 northbound. This is the element of the project that decreases air pollution and improves access to jobs, universities, and major attractions including the Providence Place Mall and the Rhode Island Convention Center.
  • New pavement and pavement rehabilitation will occur along I-95 through downtown Providence.
  • New bridge structure - The northbound structure (Bridge No. 578) will be replaced with new support piers and consistent 12-foot wide travel lanes and four-foot wide shoulders.

The benefits of the project are significant:

  • Safety and Mobility
    • Vehicle crashes are expected to be reduced by 35 percent.
    • Recurring worst case peak hour vehicle queues are reduced from 8.2 miles to 0.8 miles.
    • Travel times will improve up to 75 percent on Route 6/10, 30 percent on I-195, and 25 percent on I-95 entering Downtown Providence.
    • Wider lane widths and shoulders will measurably improve safety for disabled vehicles and maneuverability for emergency vehicles.
  • Economic Impact
    • 625 full-time construction jobs will be created;
    • spin-off, or indirect/induced job growth, is 518 jobs;
    • up to $3.2 million in annual vehicle operating cost savings from congestion relief
    • $2 million in annual economic and societal cost savings from the crash reductions
  • Improved Regional Air Quality
    • The total emission reductions are 1.9 million kg per year (carbon dioxide, nitrogen oxide, particulate matter, and volatile organic compounds).
    • The largest contributor of greenhouse gases is carbon dioxide, which is reduced by 1.8 million kg per year.
