I lived near there across from Settegast Park until 1958. That used to be Trinity Portland Cement Co. on Navigation Blvd. York and Sampson streets used to dead end at Navigation. You had to use either the Jensen or Lockwood bridges to get over Buffalo Bayou. On page 42 of the 1953 Bracy's Block Book of Houston it shows Trinity at this location. By the late 50's or early 60's there was a trailer manufacturing company there, I think they were called Croft Trailers. The cement pillars were remnants of the Cement Co. Just to the west of them was the old Houston Packing Co(meat), then west of them the City of Houston Incinerators (all that remains are the 2 smoke stacks. Prior to the meat packing plant it was used by the German society Volksfest for their fairgrounds park and festivals. Next to the city waste site on their west was at one time circa1870- 1890, the repair yards for the San Antonio & Aransas Pass R R. Around the late 1890's there was in use city mills a compress, with small cottages for the workers on tiny lots on the nearby streets (Bering, Fox, Fruend, Foley, etc. Continuing towards town there was the Dreadman (not sure of spelling) Mfg. Co. Then later on Houston Shell & Concrete had another plant next to Jensen Street Bridge. You can still see their 3 silos. Also at one time KNUZ radio had their antena somewhere along there near Pless St. It might have been near that metal quansant looking hut is, I can"t remember exactly. With the waste incinerators,the meat packing disposal incinerators, 2 cement plants belching out their smoke it could get kind of rank if the wind was coming from the North. It was much nicer when the South winds blew the Coffee smells from the old Maxwell House plant on Harrisburg. Sometimes if the East wind was just right you might get a good wiff of the Folgers Coffee plant on Navagation. All these properties bordered Buffalo Bayou. There is something I left out, but that is all I can think of at this time. Hope it is of some help.
