Biggerintersections,

more lanes to cross& increased trafficwill make walking

even more difficult.

Encourage walking

by providing safe,direct & traffic-

separated routes

The pedestrianenvironment of

Montlake Blvd isalready poor.



TOWARD A CONNECTED MONTLAKE LID

Larger intersectionscreate more conflicts for

bicycles in traffic.

Mixing pedestrians &bicycles on sidewalks

creates conflicts.

TOWARD A CONNECTED MONTLAKE LID -- 5 -- RETHINK REGIONAL PATH UNDERPASS

Widen tunnel to createseparate paths for bikes

& pedestrians.

Narrow tunnel will feelunsafe after dark.

Bicycles U-turnacross traffic

Fast moving bikeswill conflict with

pedestrians

Blind stair landingnext to tunnel

entrance.

Consider overpass option

to increase safety

Open space will feelisolated and unsafe.

Traffic lanes discourageaccess to park space.

Poor connection:Pedestrians andbicyclists must

cross ramp traffic.

Connect lid tostormwater park(see next page).

Consider ways tonaturally ventilate tunnel

& remove O&M facility.

Create multiplesmaller lids

for betterconnectivity.
