3. 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

4. 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

5. 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

6. 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

7. 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

8. Project Mobility Objectives

9. 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

10. 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.

17. 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

18. 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

19. • 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

23. 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

24. 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

25. 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

26. 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

27. 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

28. 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
