1916 Map of Midway

About this map

Midway stands as the central point of interest in this 1912 survey, situated at a vital juncture where the California landscape transitions along the Alameda Co San Joaquin Co border. The map documents the early 20th-century transportation corridor through the Altamont pass area, dominated by the parallel routes of the Southern Pacific and Western Pacific railroads. These rail lines follow the natural contours of the land, flanked by the seasonal drainages of Mountainhouse Cr and Patterson Run. The meticulous topography, surveyed by Duncan Hannegan, reveals the intricate drainage patterns and bench marks like BM 351 that defined this rural crossing before the massive infrastructure changes of later decades. This preliminary edition provides a focused look at the infrastructure that facilitated movement between the Central Valley and the Bay Area during the pre-war era.
