Canarsie Tunnel WHAT INFORMED OUR PLANNING PROCESS? Input from over - - PowerPoint PPT Presentation

Fixing the Line’s Canarsie Tunnel

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

• Ongoing Work:
• Relocation of ConEd ducts and power cables completed along

Bedford Ave.

• Currently assisting National Grid with North 7th street, high

pressure gas line reroute.

• Currently Installing SOE (Support of Excavation) – Bedford Ave

Stair South –Soldier Piles are installed and installation of walers and lagging is ongoing.

• Currently Installing SOE– Driggs Ave Stair South –Soldier Piles

are currently being installed.

• Work is currently ongoing for the new mezzanine lay out, the

exist walls have been demolished and the contractor is preparing for CMU wall installation

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:
• Broadway G and Lorimer St / Hewes St JMZ
• Junius St 3 and Livonia Av L
• 21 St G and Hunters Point Av 7
• Weekends and Overnights, M runs to 96 St / 2nd Av

PERMANENT STATION IMPROVEMENTS

Prior 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.

PROPOSED STREET TREATMENTS

BICYCLE NETWORK CONNECTIONS

Times Square Upper West Side Midtown Upper East Side Downtown

2,069 – 3,490 cyclists projected to enter Manhattan on the Williamsburg Bridge during AM rush hour (8A-9A)

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
• ption
• 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
• uter 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

DURING THE SHUTDOWN

16

OUTER ROADWAY:

• Buses
• Trucks
• HOV 3+ to Clinton St

INNER ROADWAY:

• HOV 3+ only

HOV 3+ RESTRICTIONS ON WILLIAMSBURG BRIDGE

Policy

• Buses, Trucks & HOV 3+ Only
• Manhattan-Bound & Brooklyn-Bound
• All Lanes
• Peak Hours (hours under development)

Vision Zero Priority Area with numerous calls for safety improvements

Three times expected increase In bicycle volume A reliable connection for East River crossing Numerous Buses Will Need To Operate Safely And Reliable On Grand St Dedicated truck route connecting industrial business zones to Williamsburg Bridge Curb regulations will be updated to promote commercial loading

Proposed

Proposed

Buffered Curbside Bike Lane In The Eastbound Direction Standard Bike Lanes In Both Directions

• Restricting traffic to buses and local traffic only during

peak hour periods

• Reduces road “friction” and maintains reliable
• perations 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

FERRY

Service Plan:

• Weekdays/Sunday: 6 AM – midnight

Friday/Saturday: 6 AM – 2 AM (pending NYCDPR coordination)

• Rush hours: 8 boats per hour per direction, carrying up to 1200

passengers per hour per direction

• Fares will be integrated with the M14 SBS and M23 SBS
• Transfer to these bus routes at temporary bus terminal at

Stuyvesant Cove (E 20th St and Avenue C)

• Temporary landing modifications at N Williamsburg
• Ongoing coordination with NYCEDC, NYCDOT, and NYCDPR
