This is Central City Mobility Project update #26.

Work is occurring on I Street this week. The street has been marked from 21st Street to 12th Street, and some of the white striping has been completed. No green paint yet. This section is all right side of the street bikeways.

The design is rather erratic:

• 21st Street to 20th Street, parking protected separated bikeway
• 20th Street to 19th Street midblock, bike lane
• 19th Street midblock to 16th Street, buffered bike lane
• 16th Street to 13th Street, buffered bike lane
• 13th Street to 12th Street, parking protected separated bikeway

At the intersection of 21st Street and I Street, there are markings for dashed green bike lanes on the west, south, and east legs, adjacent to the crosswalks (not yet painted). No sign of the promised bike signal yet. The markings imply to me that bicyclists continuing north on 21st Street will have to make a two-stage crossing, first across 21st Street, and then across I Street. This is not what was advertised, which was that bicyclists would have an exclusive signal phase during which they could go to any of the three destinations without any moving motor vehicle traffic. To to seen.

At 20th Street, the street becomes three motor vehicle lanes (general purpose travel lanes) and a curb-side regular bike lane. I’m guessing this is to provide stacking area for motor vehicles when trains are crossing. Makes some sense, but it also makes the bikeway erratic, and will encourage poor behavior as drivers speed into the third lane, and then have to merge back into two lanes.

At 16th Street, the street design is two motor vehicle lanes and a buffered bike lane. The reason for this is that the Memorial Auditorium loading dock extends into the street, which was an earlier design mistake that the city made to choose auditorium convenience over people walking (Sac permanently closes sidewalk).

12th Street is the end of the project, and I Street is again a three-lane traffic sewer towards the freeway. At 6th Street it becomes a five-lane traffic sewer.

Since work is actively going on today, I would guess that the white paint will be complete by the end of this week, and green paint added next week. There is still a national shortage of the green K-71 vertical delineators, so I would guess that only a few will be placed in the near future. There are a few places with gaps in the white stripes, which will be a designated color for parking or loading.
