Goals for South Shore Coalition Briefing
• Provide overview of the P3 concept, origins and benefits
• Introduce the Route 3 Express Toll Lane study • Describe study process, next steps and
interest in Long Range Transportation Plan • Answer questions
3
Why Express Toll Lanes on Rte. 3?
• Address identified safety problems
• Restore the breakdown lane to its intended use
• Improve mobility for autos and buses
• Reduce congestion 4
Public-Private Partnerships (P3): Overview • Legislature authorized P3 in 2009 Transportation
Reform • A private concessionaire leases asset for 30-50
years, implements the project and returns the facility in a state of good repair
• The financing mix can vary: • state payments; • private equity; • private loans; and • federal TIFIA loans
• Toll revenues cover financing & maintenance costs
5
P3 Advantages
• Opportunity to share or transfer risk • Ability to pursue projects in times of limited
federal and state funding • As in Design-Build projects, increased
opportunities for private-sector innovation and improved project delivery
What is Project Mobility? • Project Mobility is a study to explore Express Toll
Lanes on Route 3 South • Proposed project runs from the Norwell-Marshfield
line, north of Exit 12, to Exit 18/19 at the Braintree Split and beyond Exit 6 on I-93/Route128 in Quincy, about 17 miles
• Toll lanes would be in median with restored shoulder • Two toll-lane options are being studied:
• two-lane reversible facility (reverses a.m. & p.m.) • single, permanent dedicated lane in each direction
• Toll lane free for buses

Project Mobility Objectives
8
Key Issue is Safety: Peak Period Breakdown Lane Use
• More crashes and higher crash rate on Rte. 3 segments with active breakdown lane
• Data suggest peak-period breakdown lane use influences crash rates Rte. 3 SB: 17% more crashes Rte. 3 NB: 37% more crashes
• Project would restore shoulder for emergency use only 9
Key Issue is Safety: High-Crash Locations Throughout Corridor
Rte. 3 interchanges are on State list of the highest crash locations in Greater Boston region*
• Burgin Pkwy/Washington Street, Exit 18/19 • Union Street, Exit 17 • Main Street, Rte. 18, Exit 16 • Derby Street, Exit 15 • Hingham Street, Rte. 228, Exit 14 • Washington Street, Rte. 53, Exit 13
* MassDOT Highway Safety Improvement Program-identified crash clusters, 2011–2013 for the area between Merrimack Valley & Northern Middlesex; Central Mass., and Old Colony.

Transportation & Mobility • Express toll lanes give drivers flexibility to
choose toll lane or existing lanes • Research finds that few drivers choose to
use toll lanes all the time • Detailed traffic and revenue
studies will determine appropriate tolls • Travel time savings must be
significant to attract users and reduce congestion in free lanes
17
Operational Issues • Goal is to use pricing to manage toll lane volumes
to maintain a minimum continuous speed of about 45 mph
• Goal is to improve travel speeds in general purpose lanes by attracting drivers to the toll lanes
• All Electronic Tolling (AET) will prevent delays associated with toll plazas
• Toll pricing structure has not been established
18
• Corridor has sensitive resources: wetlands, water supplies, protected habitat
• Majority of widening is within existing right-of-way and median
• Unavoidable impacts to wetlands • Improvements to wildlife passages • Stormwater management benefits • Potential for noise barriers

Consistency with MPO Goals Safety
• Improves high-crash cluster locations identified by MassDOT
• Adds capacity to help reduce peak-period congestion and resulting rear-end collisions
• Restores breakdown lane for its intended emergency-only use which may help reduce crashes
23
Consistency with MPO Goals Capacity Management/Mobility
• Manages congestion using active lane management and congestion pricing
• Improves mobility for bus passengers with free-flow express lanes
• Improves mobility for pedestrians and cyclists with new accommodations on bridges
• Reduces congestion on arterials by improving travel time on Rte. 3

Consistency with MPO Goals System Preservation
• Helps achieve state of good repair • Rehabs or replaces 27 bridges • New pavement on existing lanes • New ITS elements
• Permanent Variable Message Signs • Fiber optic cable
• Modernizes roadway drainage
25
Consistency with MPO Goals Economic Vitality
• Modernizes and expands Route 3 to improve access to existing employment centers and homes
• Reduces auto and bus riders’ travel time
• Helps address perception of South Shore as hampered by mobility issues
26
Cost and Schedule
• Estimated construction duration: 4 years • Estimated construction cost: $600 m–$800 m • P3 procurement will induce private investment • Project must be in new Long-Range Transportation
Plan to initiate federal environmental process
27
Study Status
• MassDOT has initiated a study of engineering, traffic, financial and environmental issues
• Federal and state environmental processes to begin later in 2015
• Public and agency outreach is beginning
