Detour signs completely block the bike lane and the sidewalk on Soquel Avenue, Santa Cruz, California. This is especially sucky because Soquel is normally a very busy street with heavy bike and motor traffic. Cyclists typically move at something like 5 MPH because of the steep grade here.
Dear Caltrans District 5: I believe these signs placed by your Highway 1 Project contractor may violate Section 6D.101 on “Bicycle Considerations” in the 2012 Edition of the California Manual on Uniform Traffic Control Devices.
2012 CA MUTCD Section 6D.101(CA) Bicycle Considerations
There are several considerations in planning for bicyclists in TTC [Temporary Traffic Control] zones on highways and streets:
A. A travel route that replicates the most desirable characteristics of a wide paved shoulder or bikeway through or around the TTC zone is desirable for bicyclists.
B. If the TTC zone interrupts the continuity of an existing bikeway system, signs directing bicyclists through or around the zone and back to the bikeway is desirable.
C. Unless a separate bike path through or around the TTC zone is provided, adequate roadway lane width to allow bicyclists and motor vehicles to travel side by side through or around the TTC zone is desirable.
D. When the roadway width is inadequate for allowing bicyclists and motor vehicles to travel side by side, warning signs should be used to advise motorists of the presence of bicyclists in the travel way lanes. See Section 6G.05 for more details.
E. Bicyclists shall not be led into direct conflicts with mainline traffic, work site vehicles, or equipment moving through or around the TTC zone.
