US route endpoints in
Trinidad, CO

Originally, in 1926, Trinidad was served only by US 85 and US 350.  From the north, US 85 came in on Linden Avenue and made several turns before heading southeast on Commercial Street, southwest on Main Street, and south on Santa Fe Trail.  US 350 came in on Main, and ended at its junction with US 85 at Commercial:

US 160 made its first appearance on the 1930 CDoT map.  It seems likely that the designation would have been overlapped with US 350, sharing a common terminus at US 85 in Trinidad.  However, the Trinidad insets through 1934 suggest that the designation ended at Beshoar Junction.  On the other hand, that may have been an oversight, because the 1934 main map did indicate that US 160 had been co-signed north with US 85 through Trinidad to Walsenburg, and then west via the former US 450.  Barring further information to the contrary, we will proceed under the assumption that, until 1933, US 160 overlapped with US 350, ending in Trinidad.  This photo was taken looking southeast on Commercial:

Also, in about 1959, the US 85 (and US 87) designations were moved over to what is now I-25.  So the US 160 and US 350 designations were extended southwest along former US 85; they then ended at I-25.  In about 1992, Kit Carson Trail was built so US 160 traffic could avoid downtown Trinidad with its narrow brick streets.  Probably that was the same time that the US 350 designation was truncated to its current endpoint at Beshoar.  This photo was looking north on I-25, which curves off to the left:

(The center panel there was removed by June 2006, because exit 14A no longer exists.)  The exit to the right serves Main Street, which formerly marked the west beginning of US 350 and US 160 (when I-25 was first built).  But US 160 traffic has now been shifted to Kit Carson Trail.  After exiting there and making a right turn down by the gas station, a traveler finds themselves on the segment of Main that was the original US 85 through town.  In a few blocks, they reach an intersection with Commercial Street:

Traffic coming from the right (west on US 160) passes the sign shown here:

Today US 350 begins to the right, but historically it continued left.  That could have been the original west end of US 160, but more likely it was co-signed left with US 350 into Trinidad.  (Incidentally, one of the Spanish Peaks is visible behind the sign, as well as part of the Culebra Range at far left; both figure prominently on the horizon in this area.)

Westbound US 350 formerly continued ahead with US 160.  Continuing that way a few miles, the highway becomes Main St in Trinidad.  Today US 160 traffic is routed across the north end of town via the Kit Carson bypass, but originally highway traffic continued straight ahead on Main.  The intersection with Commercial marked the original end of US 350, and probably the first end of US 160 as well:
