The Bay Ridge Line had a stop at Myrtle Avenue that opened in 1893.
While there is no trace of it now, there is quite a bit of forested
clearance on both sides of the tracks that would probably leave room
for new subway platforms. The bridge is a 114-foot steel stringer
built in 1913. As with Cypress Avenue, there was a short platform
between the east- and west-bound tracks reached via a staircase from
street level. aRRts-Archives
had photos from when the station was active but I couldn't find any
traces of the old staircase.
The Cypress Hills Street bridge is an othewise unremarkable 78-foot
steel stringer bridge from 1913, except for some piers running along
the west side. They may have served as the elevated portion of a siding
as there are siding rails poking out of the pavement a few hundred
feet to the north. The piers now serve as parking place dividers in
the parking lot of Glenridge Mews, an upscale apartment building housed
in the old Philip Dietz Coal Company Building
