McKerrow was/is a small railway siding on the CPR branch line west of Sudbury , Ontario , south of Lake Agnew and north of Espanola . It is 1.5 km east of the Junction of the TransCanada Highway (17) and highway 6 ( to Espanola and Manitoulin Island ) . It is 3 km west of where the railway bridges the Spanish River .
At highway speed it takes almost 3 seconds to pass . There is no reason to stop... well...perhaps slow down for the turn north to Lake Agnew or south for a back way into Espanola .
