Interstate 51 is a semi-major Interstate on the dulmCraft server. It is a north-south Interstate that goes from the junction with I-55 in Soufton County to Driftwood in about 1.7km total.
One enters onto I-51 from I-55 at the northern end of Soufton County near Buc-ee's as it intersects with Bicland Route 101 for Exit`1. It goes for about 80m before one gets to Exit 2, which is for the Buc-ee's. Yet for another 80m will let one to arrive at the border of Swinescrote.
When I-51 enters into Swinescrote, it is met with Exit 3, which has two parts: a “ramp” going south to I-47, which ends at New Gaumley and Exit 3b is merely a traffic stop at Bicland Route 103, which goes to Coprophagia. Exit 4 is Interstate 3, also heading to Coprophagia as well as Soufton. After passing through the urbanized space within Swinescrote, I-51 crosses the Korgisson Swamp, a notable swamp on the server.
Exit 5 is the exit for Allantown, but an extra northbound ramp to I-51 is noticeable prior to the actual interchange. After this is a short 85m drive till one reaches the South Korgistan Tunnel. One would leave Allantown before they would get out of the Tunnel.
The South Korgistan Tunnel ends in Driftwood County, also an Exit 6 for I-51 Business, which goes into downtown Allantown. It is about 122m before I-51 Business splits off again(Exit 7), this time for Driftwood, a major Squahamian city. I-51 bypasses the city eastward in several curves before it goes straight towards its southern terminus.
