Kinzie runs east-west, side to side in this Google Street View image. The ideal viewing angle between a motorist and bicyclist is 90 degrees, which is possible for the eastbound cyclist (from right to left) and the northbound motorist (pictured, in the white car). The eastbound motorist turning onto southbound Jefferson has an acute view angle to the cyclist and motorists typically believe they can make the right turn before it could possible harm the cyclist. Making the street one-way would mitigate this right-hook problem.

Make Jefferson Street a one-way street going northbound so no more motorists will turn right onto southbound Jefferson and right-hook bicyclists going east on Kinzie Street.

It’s that simple. It should have been done four years ago when the Kinzie Street protected bike lane was created from a road diet (4 to 2 conversion). Instead, I get reports like this one. In fact, this exact scenario has played out several times since the lane’s inception, including with a truck in the first weeks after the lane opened.

I was traveling eastbound in the bike lane on Kinzie Street. A car was traveling in the same direction, but did not yield to me as it turned in front of me. I had my attention on the car in advance in case it did something like this, so I had sufficient time to slow down and avoid running into it as it turned to the right in front of me.

I’m glad this person was experienced enough to avoid the crash, but we can’t expect that bicyclists and motorists have the right experience when traveling within the city.

A two-way Jefferson isn’t necessary to provide access to the parking behind the residential building here because access can be gained from Canal (a two-way street) and the two-way driveway leading from Canal.

If maintaining Jefferson as a two-way street is imperative, then we can make some really intense infrastructure – intense by Chicago standards – and create a neckdown and raised intersection so that only one direction of traffic can cross the bike lane at any time. If there’s a northbound motorist waiting to turn onto Kinzie from Jefferson, and there’s a motorist on Kinzie wanting to turn onto Jefferson, then the Kinzie motorist would wait for the Jefferson motorist to turn.

The raised intersection is an additional traffic calming measure that also improves pedestrian accessibility.

What sucks about the state of infrastructure in the United States is the lack of understanding and knowledge about atypical designs (limited and rare examples of practical applications across the country) and this leads to deficient implementations of designs proven to work millions of times a day elsewhere.

The person who submitted this Close Call suggested more signs or a flashing overhead light. Yet those are tools that don’t actually require the motorist (or the bicyclist) to react in any way, whereas a piece of infrastructure – concrete, asphalt, and their topography – does more than just remind or encourage.

I would go so far as to suggest a policy that sets a target reduction in signage in the city, because eliminated signage must be replaced by the appropriate infrastructure. The best example? We have a law in Chicago where, if there’s a sign saying so, you cannot park a car within 20 feet of a crosswalk.

Get rid of the sign – they’re so ugly – and the need to pay attention to it by building a bumpout with a bioswale. Not only have you enforced the “no parking” regulation now until the concrete crumbles, and given pedestrians a shorter walk across the roadway, you also add stormwater infrastructure that reduces the burden on our combined sewer system.
