Unable to answer "Are there traffic signals that show when to cross here?" – Crossing – node/7863402924 via StreetComplete 62.0:

There's no pedestrian crossing of the highway, you're on the sidewalk of an overpass

There is a barrier down the median of 50 St here, to prevent east-west through traffic along 119 Ave, and also prevent left turns at this intersection. Motor traffic on 50 St can go straight or turn right, motor traffic on 119 Ave must turn right.
Bicycle and foot traffic can continue straight.

Barrier though intersection - you cannot drive East-West on 119 Ave, must turn right onto 54 st; cannot turn left from 54 st onto 119 Ave
