Beiber Info Needed

Any old GN/WP heads help with Beiber info. I am modelling '47-'50 and every little bit helps. For instance: When was the Hwy 299 overpass built? What were track designations? What were typical daily operations? Thanks, jc5729

P.S. I also need pictures of the south end and east side of the depot, and any other buildings there at that time. Thanks, jc5729
