Toll-Free Times On 405

opentoallhotlanesLast week, WSDOT changed the tolling procedure on 405. The HOT lanes are now open to everyone between 7pm and 5am and on weekends. You don’t need a pass, you don’t need multiple passengers, and you don’t have to pay money. I love this change, but I’m surprised they did it.

If you read the notes from the meeting where they decided this, it’s clear that they have a lot of data available. Some of those charts are incredibly interesting. If you’re a data nerd who travels 405, you’ll love it. But the main problem I have, as I’ve stated before, is that they aren’t optimizing just for maximum throughput on the road. You can see it in their notes. They always talk about how much money each of the options will cost them in lost revenue. The system is in place to generate money and give rich people a fast lane. I’m fundamentally opposed to that. The highway is a shared resource. Let’s maximize throughput. End of story.

So why am I surprised that they created a toll-free time? Because people are going to start realizing that the toll isn’t the part of the system that is important. The important part is having separate lanes with limited entry and exit points, just like a standard express lane setup. There are already calls for WSDOT to experiment with no-toll times during the day instead of just at night, but I can’t imagine them doing that. They’d be giving up a lot of money and that’s a higher priority for them┬áthan just improving throughput. Making it free at night and on weekends costs them 3% of their total revenue and removes traffic jams that the HOT system added on the weekends so it’s a nice PR win and actually does improve traffic. Changing the daytime rates would be a much bigger hit to their bottom line.

Seattle’s Big Dig

sr99viaductprojectSeattle is in the middle of an enormous construction project. I haven’t┬ákept up with the details, but my general impression was that it was a financial disaster. I spent a little time doing some research into the current state of the project and how far it has come:

  • The double decker highway, SR 99, going right along the waterfront is in severe need of replacement. The 2001 earthquake damaged it and it is a disaster waiting to happen. It’s also a terrible spot for an elevated highway. It runs like a big scar right along the beautiful waterfront creating a dark, gloomy, wet area that you have to walk through to get to the waterfront. The plan was to bore underneath it. You know, right next to the ocean. What could go wrong?
  • It is the widest bored tunnel ever attempted.
  • The initial budet was $3.1 billion and started in 2011. It was scheduled to be done in 2015. The tunnel boring part was expected to take 14 months.
  • At the point when the tunnel was 10% complete, the state had spent 70% of it’s money.
  • The drilling machine, Big Bertha, has moved 1437 feet. That’s about 15% of the total distance.
  • Problems so far have included the machine getting stuck, the machine breaking and needing major repairs, and the ground caving in.
  • When the machine broke, it was down for two years. There’s no way to back it out so they had to dig a huge hole to get down and repair it in place.
  • Even parts of the project that don’t involve tunneling are over-budget. Replacing the seawall along Alaskan Way was a $331 million dollar project which is already about $100 million over budget.
  • The most recent estimate I could find for completion was March 2018. Complete rebuilding of the waterfront will stretch into 2019.
  • I couldn’t find anything that gives a recent estimate of the actual cost of the project. It seems like most people just shrug, laugh and cry.

I get why people thought this was a good idea. It would be beautiful to hide all that traffic and really beautify the area, but the discussions now are not around what would be beautiful, but rather, when should they cut bait and run. And of course, if they do decide to stop, they still have the original problem of the decrepit double decker SR 99 to deal with. It’s anybody’s guess how (and when) this one will turn out.

I-405 Construction Update

i405We live right off of I-405 so we have been living with the enormous construction project for years. However, it’s slated to finish this fall and some of the details about the new traffic flow are starting to come out:

  • An extra lane is being added between NE 6th and NE 160th St
  • That extra lane along with the existing HOV lane will be “express toll lanes.” Cars with enough occupants will travel in them for free, but others can pay to travel in them.
  • During peak hours, three people are required to use the express lanes. In off peak hours, two people will qualify.
  • The rate for non-HOV users will vary based on the traffic. More traffic? Higher rate. They try to keep traffic flowing on those lanes by pricing people out of them.
  • Motorcycles are always exempt as with other HOV lanes.
  • You need a new “Flex Pass” to use those lanes. If you already had a switchable pass, you can call for a free upgrade.
  • There are defined entry and exit points for the express toll lanes.

I’m interested to see how much the extra lane helps traffic. Having the defined entry and exit points should help keep the traffic segregated a bit. For example, there’s no entry point right at 520 which will hopefully reduce some of the congestion as 520 drivers merge onto 405.

I do wonder about the sensibility of adding an extra HOV lane instead of regular lane. I really hope that it’s being done because this actually reduces commute times for everyone and not as some environmental action to try and force people to carpool.

Thankfully I have multiple routes that I can take to and from work. 405 is just one of the options. With almost 200,000 people traveling this stretch of road every day, I’m sure I’m not the only one who is eager to see how this is going to turn out.
