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

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

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

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

• Exit at next right turn

• Left turns prohibited at most intersections

• Enforceable with bus lane cameras

• 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

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
