The Challenge: 400,000 Daily Rides
225,000 between
Manhattan/Brooklyn
Nearly as many inbound
passengers as private
vehicles on all six East
River bridges and tunnels
combined during AM peak
50,000 within
Manhattan
Greater than busiest NYC
bus route (Bx12) and
66% greater than current
M14 ridership
400,000 daily rides
If the L were its own
transit system, it would
rank 11th among all North
American rail systems
Increased alternate subway service
Temporary bus service
Temporary ferry service
Station access and capacity improvements
Temporary bike and pedestrian infrastructure
Temporary peak period traffic management strategies
Our Strategy
Subway, Bus, and Ferry Alternatives for L Riders

Current Williamsburg Bridge Traffic Volume & Speed
Williamsburg Bridge: HOV 3+
HOV 3+ Policy:
5 AM to 10 PM, every day
• Buses, trucks & HOV3+ only
• Manhattan- and Brooklyn-
bound
• All lanes
• Pursuing automated
enforcement technology
• Working with NYPD for
enforcement on Delancey
Street
HOV 3+ IN EFFECT
Traffic Volume Current Taxi Speed
Delancey Street
From Williamsburg Bridge to Bowery• Continues bus priority from
Williamsburg Bridge
• L1, L2, L3 and L4 SBS will stop
at Essex St for Delancey/Essex
F/J/M subway transfer
• Provides a safe bike facility
connecting the Williamsburg
Bridge, Allen Street and
Chrystie Street
• Bike lane approved by CB 3
• Construction starts in
September 2018
Allen Street
From Delancey Street to Houston Street • Maintains the existing bike
lanes
• Southbound bus lane will
be aligned to the left to
accommodate left-turning
buses at Delancey St (left
turns for buses only)
• M15SBS/Local will be able
to use the bus lanes
• Construction starts in
October 2018
Kenmare St: Traffic Patterns
• Most vehicles on Kenmare St are going to or coming from the
Williamsburg Bridge
• ~35% of vehicles on Kenmare St are traveling to/from the Holland
Tunnel
• Westbound traffic volumes are higher than Eastbound volumes all
hours of the day
• Trucks make up approximately 10% of vehicles on Kenmare St
• During the L tunnel closure, the Williamsburg Bridge will be HOV3+
and truck only from 5 a.m. to 10 p.m., 7 days a week
• Modeling predicts HOV3+ policy will reduce traffic volumes on
Kenmare St up to 75%, depending on direction of travel0

• DOT provided two design options to stakeholders
• Two way option identified as preferred approach
• Shifts existing travel lanes to accommodate an
offset bus lane
• Full-time loading/parking in 8’ lane on the north curb
(currently a part time loading lane)
• Convert lane against the south curb to Eastbound
travel lane
• Eastbound through traffic would be constrained by
any loading activity on south curb
• Traffic analysis indicates this option is feasible
• Construction starts in Spring 2019

5 a.m. to 10 p.m., every day• Buses• Emergency Vehicles• Local access for deliveries, private
parking garages, pickups and drop-offs
• Busway hours support period of highest
traffic demand on 14th Street
• Bus lane camera enforcement and NYPD
presence will deter through traffic
• Busway operation without a midday gap
allows for clear messaging and
enforcement
• DOT will monitor traffic conditions on 14th

throughout the closure period

• Response to public and elected official
feedback
• Local access:
• Turn right on to 14th Street
• Exit at next right turn
• Left turns prohibited at most intersections
• Enforceable with bus lane cameras
14th Street: Local Access Within the Busway
• Most pickup/drop-off activity currently takes
place on the avenues, not on 14th Street
• DOT will conduct outreach to local
businesses and residents about access
policy
Bicycle Network: Connections
2,000 – 3,500 cyclists projected to
cross the Williamsburg Bridge
during AM rush hour (8A-9A)
Existing: Wide travel lane
Blocks range from 29’-34’ wideProposed: Curbside bike lane on left side (south side
of 13th St, north side of 12th St)
Bicycle Network: 12th St & 13th Street
• Temporary bike lane separated with
flexible delineators and demarcated
buffer
• Floating pickup/drop-off adjacent to bike
lane may be feasible at some locations
• Parking spaces to be removed along
• North side: 12th St (7th Ave – Ave C)
• South side: 13th St (Greenwich Ave
– Ave B)
Increasing docks and bikes: 1,250 bikes, 2,500 docks
• Manhattan: 59th Street – Canal
• Brooklyn: Williamsburg-area
Expansion in Bushwick
Expanded Valet Services
• Staffed by Citi Bike, Valet Service allows Stations to
operate at increased capacity
• Pedal-assist Shuttle Service
• 1,000 pedal assist bikes
• Available at key locations
• 2 in Manhattan
• 2 in Brooklyn
Additional standard bike parking in key locations
Outreach to Community Boards in October
Bicycle Network: Citi Bike Infill
Where We Are Now: Keep the Feedback Coming
100+ public meetings (with more coming)
5,000+ comments received (and still counting)
Thanks to your input, we’ve:
1. Maintained local pickups/drop-offs on 14th St
2. Maintained two-way traffic on Kenmare St
3. Added the L4 bus route
4. Added a new L1/L2 bus stop in Brooklyn
5. Changed our plan to a pair of one-way
crosstown bike lanes (instead of one, two-way
lanes)
6. Added the L5 bus route
From the beginning, you helped us decide:
• Tunnel construction with 2-track closure
• Ferry hours of operation
Where We Are Now: Environmental AssessmentFederal Transit Administration (FTA)
finalized its assessment of the temporary
transportation options which resulted in a
“Finding of No Significant Impact”
Highlights:
• Buses
• 5 electric and 10 hybrid diesel-electric
buses by April 2019 for the inter-borough
routes
• 15 articulated electric buses to follow in
Q4 2019 for M14 SBS
• Environmental quality monitoring
• Construction monitoring underway
• FTA did not require mobile source
monitoring, however we are working on a
plan with an environmental consultant
What’s Next: Weekend Preparatory Work
• Part of the current pre-tunnel closure construction
plan
• Running shuttle service normal for L weekend work
• 2019 weekend dates to be finalized soon
• We are using these weekends to:
• Do maintenance on the L track that will remain in
operation
• Prep the construction site with lights, wireless access
and more
• Create the stairs and elevator shaft to use for
materials input
• Ready the signals for Bedford Av to become a
terminal station
Upcoming in 2018:
October 6-7
October 13-14
October 20-21
October 27-28
November 10-11
November 17-18
What’s Next: Milestones
Ongoing Through 2020
• Construction at street level
Fall 2018 – March 2019
• Stakeholder outreach, design
and service plan refinement
• Multiple weekend and
overnight L closures to prepare
for tunnel closure
Winter 2019
• Completion of temporary street
and/or site modifications for
SBS service, bus terminal and
parking and ferry operations
April 2019
• Start of L tunnel closure,
alternative service plan begins
