The section of Pennsylvania Avenue -- from 27th Street to Southern Avenue -- will get a median, new curbs, a gutter, pavement, landscaping and upgraded utilities.
The project will also include improvement of signal operations and the construction of three rain gardens.
It won't include bike lanes, as originally planned to in 2007. Instead it will include a 10 foot wide multiuse path from Maryland to Fairlawn Avenue (most of the length). A design with bike lanes along the whole length was among the three alternatives considered, finishing above a 5 lanes with reversible lanes design, but below the 4 lanes with a median and mutli-use trail (plan is a big pdf). I'm surprised that the bike lane option did poorly on the MOVE goal to "Create a sustainable transportation network, with many travel options" and only did well on cost.
The plan calls for the multi-use trail to be on the south side of Pennsylvania for most of the way - from the District boundary to 28th street. At 28th Street a diagonal crosswalk will be installed and an exclusive bike/pedestrian crossing phase would be included in the traffic signal at that intersection. Then the trail will be on the north side up to Fairlawn Avenue where it will cross Pennsylvania again and connect with a signed bike route.
Most of the way the trail would be buffered from the street by an "amenity zone" of tree boxes, etc...But for a few short sections it will be right up against the street because the road is too narrow.
It doesn't look like the actual project will match the plan; namely in the L'Enfant Square area where a redesigned square was designed to create a pedestrian zone. What is being built now doesn't appear to have the redesigned square or the multi-use trail on the north side. The trail appears to end at 28th, so it's hard to say if the diagonal crossing will be included either.
Not sure why the trail was dumped in this section, but that section has a 28' median. Maybe DDOT could slim that down to 14' and add two 5' bike lanes?
