Eyes on the Street: Clybourn Curb-Protected Bike Lanes Are Halfway Done

Just over a month ago, the Illinois Department of Transportation started constructing curb-protected bike lanes in Old Town, on Clybourn Avenue between Halsted Street and Division Street, and on eastbound Division between Clybourn and Orleans Street. They’ve already made significant progress on the northbound section of Clybourn.

In most sections, the curbside bike lanes will be protected from motorized traffic by a three-foot wide curb plus a lane of parallel-parked cars. Even though the project is far from complete, cyclists are already taking advantage of the safer bikeway by riding in it.

It’s notable that the IDOT is spearheading this project, with assistance from the Chicago Department of Transportation, because IDOT has blocked CDOT from installing protected bike lanes on state-jurisdiction roads within the city since 2011. That changed after cyclist Bobby Cann was struck and killed by an allegedly drunk, speeding driver at Clybourn and Larrabee Street in May of 2013. We’ll have an update on the criminal case against the driver, Ryne San Hamel, later today.

While the state hasn’t fully lifted their ban on PBLs, in response to the Cann tragedy, they agreed to “pilot” the new bikeway. This will be only the second location with curb-protected lanes in the city – CDOT installed a similar facility on Sacramento Boulevard in Douglas Park in May of this year.

Crews are also currently working on the curb-protected bike lane on eastbound Division. This section includes a bus stop island – CTA riders cross the bike lane to access the bus stop. It appears that this is Chicago’s first bus stop island, but CDOT is also building a handful of island bus stops adjacent to a protected bike lane on Washington Street as part of the Loop Link bus rapid transit project in the city center.

Two apparent water management design flaws in the project could make the bike lanes a wet ride after rain storms. Although the parking lanes are capped with concrete-enclosed bulbs that would be ideal for bioswales, it looks like the designers passed up this golden opportunity to use landscaping to capture, store, and filter stormwater to reduce the burden on our already overloaded sewer system. In a summer 2014 presentation [PDF], IDOT and CDOT explicitly mentioned that the project would provide “potential for…green infrastructure” and “water infiltration applications.”

CDOT installed bioswales on Berteau Avenue as part of a neighborhood greenway but it looks like the bulbs on Clybourn are simply filled with asphalt and stamped to look like bricks. We’ve contacted IDOT and CDOT to double check that these bulbs don’t include water-management features and will update this post if we hear from them.

Additionally, rain that falls in the mixed-traffic lanes and parking lanes will be channeled into the bike lanes, where the existing sewer grates are located. Since the bike lanes will be surrounded by curbs, it will be difficult for cyclists to avoid riding through any puddles that form if the sewers fill up or the grates get clogged. This problem isn’t inherent to curb-separated bike lanes. Relocating the sewer grates and/or raising the bike lane above street level would have addressed this issue.

Last year’s presentation showed bike-specific traffic signals at the intersections of Clybourn/Division and Division/Orleans, where there will also be a protected right turn lane for bicyclists. After workers complete the northbound and eastbound bike lanes, they’ll construct the southbound and westbound lanes. The short westbound lane will have a curb as well, except between Orleans and Sedgwick Street. IDOT expects to wrap up construction in early August, according to a press release [PDF].

While there are currently buffered bike lanes on Clybourn between North Avenue and Belmont Avenue, it appears that the stretch of Clybourn between North and Halsted, next to the CTA’s North/Clybourn Red Line station, is not getting any bikeway treatments.

Update 7/28/15, 4:30 p.m. Asked whether the bulbs at the ends of the parking lanes include any stormwater mitigation features, IDOT spokesman Guy Tridgell provided this statement:

The use of permeable pavers at various locations along the project was considered, but ultimately not included, mainly due to added cost and maintenance. As part of the pilot aspect of this project, roadway drainage is one of the aspects that will be monitored in the future.

    I genuinely cannot wait to ride on this.

    I’m curious about what this cost. The only mention I could find was a Redeye piece from 2014 that estimated it would run about $500,000, but I can’t imagine that’s right, both because it’s the Redeye, and because that’s not even three times what it costs to paint polka dots on a single intersection.

  • The Lincoln Hub cost $175K and, in addition to the paint dots, it includes flexible posts, concrete seating units, cafe seating, and concrete planters.

  • cjlane

    Poking around the IDOT website, I found the bidding list:

    CONTRACT: 60X69
    DISTRICT: 01
    KEY RT: FAU 3536
    SECTION: 2013-081I
    Bikeway channelization, concrete median, bike signals and restriping on Clybourn Ave. from IL 64 (North Ave.) to Division St. in Chicago.

    and the notice of letting:

    ITEM NO. 018
    CONTRACT NO. 60X69
    SECTION 2013-081I
    AWARDED DATE 05/14/2015
    AWARDED AMOUNT $696,558.10

    So, the $500k was wrong, but not as wrong as one might think.

  • You can ride on it right now going northbound. I rode it on Saturday. It was neat!

  • cjlane

    oh, and a thought about the lack of bioswales, or any other drainage accommodations:

    making that would right would have involved some amount of revision to the slope of the road and/or locations of inlets, which would have increased the cost by much more than the semi-permeable pavers that were rejected on the basis of cost.

  • Bodega Mayback

    I ride Clybourn often and am stoked for the comfort this will provide. I have a feeling motorists will complain about the width of these curbs though. For the most part they are 2 or 3 feet wide, which is fine, but there are vast sections where they are like 6+ feet wide. I don’t see the point of this. It doesn’t seem to protect the cyclists more, it just creates less parking and a narrower road. In the third image above it looks like a whole other parking spot could be provided without eating into the pedestrian refuge area. In the second picture above it looks about 10 feet wide for at least 100 feet. Way more than needed for a bus stop. What’s the point besides eating up more of the road? They could have easily made more space for commuters on bike or in cars.

  • Anne A

    I was just thinking that a bioswale/permeable pavement treatment similar to what was done on Blue Island might have been good here. Maybe in a future revision….

  • Christine Price

    Awesome! I just wish that the bike path was wider, to make passing people with trailers and such easier. I don’t get why the median needs to be 3 feet wide. To prevent dooring?

  • lindsaybanks

    One possibility is that less roadway / asphalt costs less to maintain. I’ve been looking into narrowed streets as a way to reduce costs for municipalities. Even when the roadway is converted to asphalt parking, it still needs regular maintenance and that’s a huge part of our city’s budget. I have no actual insight into this, but it would be an interesting direction for CDOT.
