I boarded at the first stop in Williamsburg, Lee Avenue and Taylor Street. We headed south on Lee Avenue, passing many Hasidic businesses, and stopping at each B44 stop. We crossed over the BQE, and continued south to Middleton Street, where we turned left, and made a pretty nonsensical stop to pick someone up in the middle of the intersection.

After that... interesting stop, we merged onto Wallabout Street, now following the B48. We continued along Wallabout Street, getting more and more industrial, until we veered onto Kent Avenue. We crossed under the BQE, then turned left onto Willamsburg Street West (the frontage road for the BQE) and passed a small park.

 We then took the on-ramp onto the BQE. Express section time! Except... it's the BQE, so traffic. We sat in traffic for a while, inching thorugh Fort Greene and passing under the Manhattan Bridge. Traffic sped up slowly as we passed DUMBO and its new high-rises. The traffic jam finally ended after DUMBO, and we headed south

We quickly passed under the Brooklyn Bridge, before getting a nice view of Downtown Manhattan's skyline from Brooklyn Bridge Park. We passed over Atlantic Avenue, and then descended into an open cut past the brownstones of Cobble Hill. Soon, we exited the open cut and proceeded into the messy interchange with the Brooklyn-Battery Tunnel.

We then crossed over the Gowanus Creek on an insanely overbuilt bridge, and then took exit 24 onto the Prospect Expressway. We went into an open cut for a bit, then took exit 4 to 10th Avenue, where we turned right and headed southwest for a block before turning left on McDonald Avenue. We headed south, with Greenwood Cemetery on the right, and mostly single family homes on the left.

We then turned right onto Fort Hamilton Parkway, paralleling Greenwood Cemetery, with auto body shops on the left. At 37th Street, Greenwood Cemetery ended, and the road became more commercial, with shops lining both sides. We continued down this retail stretch before reaching New Utrecht Avenue, and passing under the D train.

Soon after this, we passed Maimonides Medical Center, which coincidentally, the bus's wrap was related to. We then turned left onto 50th Street, following the route of the B11, and passing mostly two-story apartments. We passed under the D train again at 12th and New Utrecht Avenues, where there was a burst of retail, before continuing east past more apartments, mostly three-story.

Continuing east, we passed a large yeshiva on 14th Avenue, where a lot of people got off. We then continued along leafy 50th Street to 18th Avenue, where the bus turned left to its last stop, on 18th Avenue, shared with the B8.
