Eyes on the Street: 2-Way Protected Lane Is Taking Shape on Clinton

About three years ago, the Chicago Department of Transportation blazed a new trail by repurposing a lane of Dearborn Street to create the city’s first two-way protected bike lane. Now they’re building a similar two-way lane on Clinton Street as part of the Loop Link bus rapid transit project. After a few years of new bikeway designs, such as the Clybourn Avenue curb-protected lanes, the Clinton lane seems less game-changing and more like business as usual, but it has a few novel elements.

The Loop Link corridor includes dedicated bus lanes on Clinton, Canal Street, Washington Street, and Madison Street. One-way protected bike lanes will be constructed on Washington and Randolph, with the latter replacing a conventional lane that used to exist on Madison.

While the bus-only lanes on Washington and Madison are paved with red-dyed concrete, the bus lane on Clinton has simply been marked on the existing asphalt with red thermoplastic. The Clinton bike lane is marked is being marked with green thermo.

The two-way lane runs will run from the Harrison Street protected bike lanes up to Fulton Street, which is part of a route between downtown and Milwaukee Avenue, the city’s busiest bike street. The section of Clinton south of Randolph is largely finished; a crew was striping the northern stretch this afternoon.

For the first time in Chicago, the entire bikeway will be green, except for at the intersections, where it will only be marked with white dashes. Hopefully, all-green bike lanes will become the standard here in the future, since color makes it more likely that motorists will notice and respect the lanes.

The green thermo will also provide a warning to pedestrians, so they don’t inadvertently step into bike traffic. As on Dearborn, “Look Bikes” has been marked at the crosswalks on Clinton, so people on foot aren’t surprised by northbound cyclists on the otherwise southbound street.

CDOT is using a new kind of flexible post on Clinton, which is tubular, and shorter than the type than they’ve typically used to delineate PBLs. They seem a bit sturdier as well, and they’re spaced relatively tightly near intersections, with about ten feet between the posts. That should discourage drivers from entering the bike lane before making left turns.

Between Madison and Randolph, the contractor erroneously striped the dashed yellow line that divides the bike lane, so that it’s left-of-center. CDOT says that will be corrected soon, but it’s actually not a bad layout, since it gives northbound cyclists plenty of room to stay out of the gutter.

Bike-specific traffic signals have already been installed on Clinton, but they’re not activated yet, so the bike lane is still barricaded. However, I saw plenty of cyclists riding in the lanes already. That suggests the new bikeway will be quite popular once it’s officially open for business.

Update 10/14/15: Although the protected bike lane currently terminates at Jackson Boulevard, it will be extended south to Harrison next summer, after work is completed on the Union Station Transit Center.

  • This is great! What happens south of Jackson, John? The map above shows the green lane continuing south, but the story says it ends at Jackson.

    We really need protected bike lanes to link the Loop to the South Side. Canal Street helps but falters north of Harrison.

  • Good point. I didn’t see any evidence of bike lane construction south of Jackson but, yes, I believe the lane will eventually be extended south to meet up with the Harrison protected bike lanes. I’ll double check with CDOT.

    The red dye on Clinton, like the green, was applied using a method I had not seen before.

    They applied new asphalt, then used some tool to create a striated pattern on it. Then applied paint over that. Riding your bike over the green (and red) dye, you can tell the difference v. riding over standard new asphalt. It’s subtle, but it feels nice.

    Also, I do not believe that either one is thermoplastic.It is just “regular” paint.

  • Workers told me the green and red markings are thermoplastic.

  • duppie

    Those must be the same workers that painted the yellow stripes down the middle of the green lane…

  • Cameron Puetz

    Thermoplastic trends to be slippery when wet, and down right treacherous with a frost. It’s not really an issue with lane markings because you pass over them so quickly, but it’s noticeable with larger symbols. I certainly hope that the green covering the entire lane isn’t thermoplastic.

  • They’re thermoplastic, though supposedly they’ve “solved” the traction issue with a surface texture/grippiness of some kind.

    I’ll believe it when I see it.

    There is a PBL on Canal at least through Roosevelt. (I’ve worked in that area for the past 9 years and went past there today.) I don’t think it’s protected south of Roosevelt, but it’s less of an issue since the traffice signicantly decreases.

    My challenge went coming across the West Loop (Canal / Clinton / Jefferson) was always that the light timing was awful. It was impossible to actually go more than a block or two because the lights appeared to be timed to mostly most cars to and from the highway.

    Also, Canal around Union Station is a mess, but I understand that should be addressed somewhat by these changes and BRT. (At least they’ve moved the Megabus station.)

  • Yes, there’s a PBL on Canal from Roosevelt to Harrison. That’s three blocks.

  • Bernard Finucane

    The yellow stripes are halfway between the parked car and the curb. Maybe the bollards weren’t in place when they were done.

  • According to CDOT, the lane will be extended south to Harrison next summer, after the Union Station Transit Center is completed. I’ve edited the post accordingly.

  • Thanks so much for looking into that, John.

    As of this morning, they have been fixing the situation in that last picture. Turns out that the striped area to the left was too wide, It looks like they are going to widen the green lane.


Take a Virtual Ride on the New Randolph Protected Bike Lane

An important new downtown bikeway recently became rideable. The Randolph protected bike lane runs from Michigan to Clinton, making an already-popular westbound route out of the Loop safer. The project involved a road diet. One one the three travel lanes on Randolph was converted to make room for the bike lane and its striped buffer. […]

Central Loop Busway Will Reorganize, Expand Downtown Bike Lanes

Bicycle routes through the Loop suffer from “poor connectivity,” admits Mike Amsden, assistant director of transportation planning at the Chicago Department of Transportation. At yesterday’s Mayor’s Bicycle Advisory Council meeting, Amsden revealed details about how the Central Loop BRT project will improve the situation by spring of 2015. The Central Loop BRT project, Amsden said, will “move people […]
