Alabama Dept. of Transportation wanted to do something special with this unique part of their transportation network (and HMS wanted to help)!

A Unique Transportation Network

From Humble Beginnings! First 100% Electric Powered Car Ferry in the U.S.!

SLIDE 6

– Pristine area of Alabama that relies on natural resources and needs preservation – The ferry is historically significant and an important symbol of the region’s progress in Civil Rights – Culturally rich and home to the famous Gee’s Bend Quilters – The economically depressed area would benefit from public and private investment – Alabama Dept. of Transportation (ALDOT) wanted to do something special with the Ferry

Minimum energy consumption is key!

– Short route (1.45 NM) – Slow speed (5-8 kts) – 10 runs/day – 30 minute load/unload leave time to charge – Power available on both sides
