The world 's first atomic bomb , in unassembled pieces , traveled through Belen in July 1945 en route to the Trinity site at what is now White Sands Missile Range . The bomb 's Belen route used old Highway 85 , now Highway 314 , also known as Main Street . Located in downtown Belen in 1945 was Roy 's Cafe , a restaurant where military and science personnel would go to grab a meal , since it had the necessary security clearance . Local legend suggests personnel escorting the atomic bomb , and perhaps the bomb itself , stopped at Roy 's Cafe as they passed through town
