Fixing the Line’sCanarsie Tunnel
1
WHAT INFORMED OUR PLANNING PROCESS?Input from over 40 community meetings
Most frequent comments:
• Buses need dedicated lanes
• Provide multiple options, including ferry
• Simple, direct inter-borough bus routing, connecting to
subways
• Bike lanes should be physically separated
• Street treatments should take emergency vehicle and
delivery access needs into consideration
• Manhattan residents fear traffic spillover on narrow, mostly
residential side streets
• Balance the needs of riders, residents and businesses.
Technical Analysis:
• Current travel patterns
• Traffic and transit modeling
• Testing of multiple scenarios.

SANDY DAMAGE
The Canarsie Tube was inundated with saltwater during Superstorm Sandy causing corrosion of cabling, circuit breakers and power and track equipment.
The tunnel needs a complete overhaul
Contract for Tube repairs awarded (April 2017)
15 Month Closure remains on schedule to begin April 2019
Bonus for early completion & $400,000-per-day penalty for delays

Bedford Av and Rockaway Pkwy
6-minute frequency

CHALLENGE OF SERVING L CUSTOMERS
A total of 400,000 daily riders use the L:
− 225,000 use the Canarsie Tube under East River
− Nearly as many inbound passengers during the AM peak hour as in
private vehicles on all six East River bridges and tunnels combined
− 50,000 travel solely in Manhattan
− Greater than busiest NYC Bus route (Bx12 - 48,000 riders/day)
− 66% greater than current M14 ridership (30,000 riders/day)
− 125,000 travel solely in Brooklyn
OUR STRATEGY

Temporary ferry service
Temporary bus service
Increased alternate subway service
Station Access and Capacity Improvements
More bike and pedestrian infrastructure
Peak period traffic management strategies
7
SUBWAY SERVICE• Subway service increased on GJMZ
• JZ trains run local from Myrtle Av to Marcy Av to serve
additional demand at Hewes St, Lorimer St, Flushing Av
• Free MetroCard transfers between:
o Broadway G and Lorimer St / Hewes St JMZo Junius St 3 and Livonia Av Lo 21 St G and Hunters Point Av 7
• Weekends and Overnights, M runs to 96 St / 2nd Av

PERMANENT STATION IMPROVEMENTSPrior to the tunnel closure, we are improving access to and capacity in stations along the , , and lines, that will provide alternatives to service. During the tunnel closure, we will also enhance stations along the line.

HOW TO MAKE L TRAIN CROSS-RIVER BUSES WORK
12
• Combined frequency of about 70 buses per hour in
peak
• Target: end-to-end bus run times of about 25
minutes
• Near free-flowing speeds across the bridge
13
IF WE DO NOTHING
• Highly variable travel times across Williamsburg
Bridge: 10-40 minutes in AM Peak
• Buses will be stuck in traffic and not be a reliable travel
option
• Reduces some crowding on the J and M trains
• Some transit riders shift to for-hire vehicles, adding to
existing congestion
• Peak hour demand for ferry will exceed capacity
Doing nothing is not acceptable
14
OUTER ROADWAY:• Not wide enough for two true
lanes when buses, trucks are
present
• Queues for heavy right turn at
Clinton St in Manhattan lead to
spillback congestion
INNER
ROADWAY:• Buses and trucks not
permitted on inner
roadway
• Traffic from BQE and local
streets backs up past
inner/outer roadway split
WILLIAMSBURG BRIDGE: EXISTING CONDITIONS
15
HOV 3 restrictions on
all lanes are necessary
to reduce traffic volume
enough to make bus
lane work
• Shifting 2,200+ cars currently using
outer deck to inner deck for a bus
lane would lead to very long queues
spilling on to local streets
• Even with bus lanes on approach
streets, traffic sorting at ingress and
egress of bridge slows buses to “do
nothing” speeds

Both Directions
• Restricting traffic to buses and local traffic only during
peak hour periods
• Reduces road “friction” and maintains reliable
operations for shuttle service
• Local bus service on Grand Street will remain
• Provides a safe bike facility eastbound and westbound
GRAND STREET DESIGN
Maintain parking and
loading along the
south curb
21
TRAFFIC MANAGEMENT PLAN
Grand St Will Be Restricted To Buses And Local Traffic Only During Peak Periods (To Be Determined)
• Short segments of bus only lanes on either side of the shuttle route will divert traffic off of Grand Street
• Traffic traveling eastbound from the Williamsburg Bridge offers a variety of options for turning off Grand Street
• Westbound traffic will be able to use Metropolitan Avenue to access the bridge
• Local traffic will be able to access Grand St via the side streets
• Further traffic analysis and curb regulation changes on Metropolitan Avenue, Grand Street, and adjacent cross streets

Problem
• Curb and sidewalk parked with NYPD school safety agent cars
• Frequent double parking and truck traffic limits access and throughput
• Right turn from Grand Street onto Waterbury Street will be tight for buses
Recommendation
• Updated curb regulations
• Convert to one way southbound

FERRYService Plan:
• Weekdays/Sunday: 6 AM – midnightFriday/Saturday: 6 AM – 2 AM (pending NYCDPR coordination)
• Rush hours: 8 boats per hour per direction, carrying up to 1200passengers per hour per direction
• Fares will be integrated with the M14 SBS and M23 SBS
• Transfer to these bus routes at temporary bus terminal atStuyvesant Cove (E 20th St and Avenue C)
• Temporary landing modifications at N Williamsburg
• Ongoing coordination with NYCEDC, NYCDOT, and NYCDPR
