At Ogden Avenue, where the bike lane ended but continues 1.5 years later. 

One of the first protected bike lanes to be installed was Jackson Boulevard, back in 2011. Although the Jackson ptoected lane was originally slated to extend from Western Avenue to Halsted Street (1.5 miles), with some buffered bike lanes within that section, construction stopped at Ogden Avenue while the Chicago Department of Transportation (CDOT) finished design negotiations with the Illinois Department of Transportation (IDOT). The state transportation department has jurisdiction over the segment from Ogden Avenue to the end of Jackson at Lake Shore Drive (Route 66), and IDOT wanted more info about the proposed lane from CDOT.

More than 1.5 years after the original bike lane installation on Jackson, the missing segment got its buffered, instead of protected, bike lane in December.

The segment between Ashland Avenue and Laflin Street, an historic district, is too narrow to have a bike lane without removing a travel lane so CDOT installed shared lane markings instead. If more people start riding bikes at the intersection of Jackson and Ashland, I foresee many conflicts at two points: drivers must turn left from the left-most lane across the bike lane path or from the bike lane itself; drivers and bicyclists going through will meet each other on the opposite side of Ashland as they head straight to the middle of the same lane on Jackson.

As is often the case in Chicago, some drivers are using the new buffered lane on Jackson as a parking lane.

Where people riding bikes need a dedicated lane most on Jackson is east of Halsted, approaching Union Station, past the Chicago River, and towards the Financial District, State Street, and Wabash Avenue. Aside from the addition of new bike-friendly concrete infill on each side of the metal grate bridge, there are no plans to extend the Jackson bikeway east of Desplaines Street (the first street east of Halsted). The one-block extension to Desplaines Street, which has some semblance of a protected or buffered bike lane where it meets Jackson, is listed in the Streets for Cycling Plan 2020 as a “Crosstown Bike Route” to be installed between May 2013 and May 2014.
