Several people encouraged the use of narrow, substandard bike lanes in an effort to get something on the street, rather than using sharrows in the wide lane, or just leaving the lane unmarked. I believe we need to be very careful to not create “bike lanes at any cost,” and to carefully consider the actual roadway conditions before specifying anything that does not meet or exceed standards. The diagrams below are from the NACTO Urban Bikeway Design Guide. The first shows a high quality bike lane adjacent to a curb; the second one shows sharrows rather than a bike lane where there is not sufficient roadways width.
This is a follow-on to The I Street mess, and is another example of poor sharrow placement. Thank you, Elle, for reminding me to write about this. On I Street between 7th and 6th streets, there is a floating bike lane on the north side. A floating bike lane, also called a part-time bike lane, is […]

As an example, 9th Street (one-way southbound) and 10th Street (one-way northbound) were converted from three lanes to […]
