About two blocks after crossing railroad tracks, turn RIGHT or EAST on US-14 (4th St.) 
Stay on US-14 (4th St.) for just over 1 mile.  Cross the James River.  Take the first possible right after you go UNDER a bridge.  Immediately turn right again on what appears to be a service road.  After about three blocks, the driveway for the church is on the right immediately after a road merges on the right side. 

From North or West (Aberdeen, Pierre, Wolsey direction): 

To Huron: Coming from the north or west on US-14 or US-281 will take you through Wolsey, SD and then US-14 will bring you into Huron.  3.5 mi. south of Wolsey, turn LEFT or EAST on US-14. Go another 12 miles into Huron.
At Huron:  Continue going East on US-14 across the north end of Huron (crossing railroad tracks twice).  Go straight through the SD-37 intersection. Cross the James River.  Take the first possible right after you go UNDER a bridge.  Immediately turn right again on what appears to be a service road.  After about three blocks, the driveway for the church is on the right immediately after a road merges on the right side. 

From East (Brookings, I-29 direction): 

To Huron: US-14 all the way. 
At Huron:  Right before reaching Huron or crossing James River, take the ramp to use the bridge to go over US-14.  It is the only bridge over US-14 anywhere near Huron.  The ramp is near a truck stop/convenience store.  After crossing US-14, immediately take the first possible right for the driveway for the church.
