DDOT recently completed some updated, or new, standards for things like sidewalks and bike lanes. It's a little wonky, unless you're passionate about the dimension off a "brick sidewalk setting bed" (1.25 inches of sand max! Time to fire up the angry email machine.) But it does include some things of interest to cyclists.
For example, here are the bike lane striping standards at intersections:
Bicycle Treatment at Intersections
But perhaps most interesting is the new standard for a bike lane closure due to a work zone.
Bike lane closure
Protected bike lane closure
2-way Protected bike lane closure
It also includes striping for a one-way and two-way protected bike lanes with parking, installation and design standards for bike racks, on-street bicycle parking standards - both near the corner and mid-block, and symbol and signage standards.
