Bridge Replacement - Detour

There is a detour on Brown County Hwy 16 south of Columbia, due to a bridge being replaced. If you are planning on visiting the refuge within the next few months, and will be accessing from the south, you will need to take an alternate route.

Alternate routes to Sand Lake NWR:

Go north on Hwy 281 from Aberdeen until you reach Hwy 10. Go east on Hwy 10 until you reach Brown County Hwy 16. Go south 3 miles until you reach the refuge entrance. 


Go north on Hwy 14 from Aberdeen (at the RDO/Titan Machinery corner) until you reach Hwy 11. Go east on Hwy 11 until you reach Hwy 16. Travel north on Hwy 16 for approximately 8 miles until you reach the refuge entrance. 

Please contact the Sand Lake office if you have any questions.
