How Does Mercer Island Commute?

Just saw an excellent post in the Seattle Bike Blog on how Seattle commutes. Which got me wondering how Mercer Island commutes.

I went to the Census American communities Survey, just released for 2012, and looked at Mercer Island versus Seattle, Bellevue and all of King County:

How-Mercer-Island-Commutes

In only a few minutes with the data a few things popped out:

1.Islanders drive more than the rest of King County.

2. Our mean commute is lower than Seattle, Bellevue or all of King County, probably because of how central the Island is.

3. Almost 10% of Islanders work from home, quite a bit higher than the rest of the county.

4. Islanders take public transportation at a much lower rate than the rest of the county. I think we’d take it more if we could get to the Park & Ride more easily or find parking there. These days, it’s parked up before 8 am, causing a stressful morning for anyone planning to get a spot.

My husband and I have tried many of these methods– driving alone, carpooling, the bus, and biking– at different times. Basically anything other than walking. One of the nice things about Mercer Island is you can get almost anywhere, fast.

I wonder how these numbers will change when the Express Lanes give way to Light Rail. One would expect a dramatic drop in driving alone and a rise in public transportation. We’ll see in about 10 years.

What’s That Barge Off I-90 Doing?

It’s the WSDOT removing and replacing “30 frayed and corroded anchor cables that hold the bridges in place on Lake Washington during windstorms.”

Cable cross section. Thanks Mike Murphy and Flickr.

Here’s the cool part:

“Unlike a typical road project, much of the work to replace anchor cables will be out of the public eye. Specially-trained commercial deep-sea divers will haul the cables as deep as 200 feet, remove the old cables and attach the new ones. A barge will be standing by with an on-board decompression chamber to treat divers after they resurface. Once each new cable is connected to its anchor on the lake bed, workers can fasten them to the floating bridge pontoons. Each cable takes about a day to replace.” From Mike Murphy at WSDOT.

Specially trained divers! On-board decompression chambers! Barge standing by! ┬áTHAT’S SO COOL.

Keep an eye out as you drive over I-90 for divers surfacing from the deep.

Groundbreaking: 24-hour HOV Capacity on I-90

We’re one step closer to 2-way, all way HOV and Light Rail on I-90. Sound Transit and the WSDOT broke ground on Stage 2 of the new HOV lane and East Link light rail project. Here’s what it’ll look like when it’s all done:

From the press release:
“The new HOV lanes and HOV direct access ramps will help improve the speed, safety, and reliability of buses that use I-90, and will help meet the growing demand of transit users on both sides of Lake Washington. Currently, buses and carpools traveling I-90 in the off-peak direction often are stuck in traffic because the reversible center express lanes operate only in the peak direction (westbound in the morning and eastbound at night). The new HOV lanes between Seattle and Bellevue will offer 24-hour HOV capacity both eastbound and westbound. HOV direct access on- and off-ramps will enable buses and carpools to access the HOV lanes without crossing other lanes of traffic.”

“The second stage of the project now getting underway will add a new eastbound HOV lane between Mercer Island and Bellevue. The first stage of the project opened in 2008 with new westbound HOV lane between Bellevue Way and 80th Avenue Southeast on Mercer Island and improved HOV access in Mercer Island and Bellevue. The third and final stage will add HOV lanes to both directions of I-90 between Mercer Island and Seattle, clearing the way for light rail to be constructed in the center lanes.”

Here’s a photo from the groundbreaking (thanks Andrew Schmid at Sound Transit for sending):

There’s nothing ten people in suits with shovels can’t build.

Just Out: Drawings of Mercer Island Light Rail Station

Looks like the link rail station will take over the Express Lane entrances downtown. A nice design that leverages the current configuration:

Daily Journal of Commerce has more drawings. Anyone got a subscription?

In MI Reporter’s summary of the Sound Transit hearing, sounds like there was a lot of bellyaching: “Others, too, asked about the center lanes with concerns about fire and emergency access, disruption and noise during construction and access to the park and ride and transit during the day.”

The truth is that nothing I’ve heard about the current plans address that fact that you can’t park at the MI Park and Ride. But since we’re not getting Light Rail til the ’20s we’ve got some time to stew on it.

I-90 Express Lanes Traded for Light Rail and a Player to be Named Later

This just in: I-90 Express Lanes will be converted to Light Rail. Sound Transit will fund new car pool lanes over I-90.

I can’t tell from the Seattle Times article if Mercer Island residents will be able to use the car pool lanes like the Express Lanes, but use of the term “car pool” makes me think not.
