As unfavorable economic conditions continue to linger, Maine DOT continues to explore means to improve fish and aquatic organism passage utilizing cost-effective structures while continuing to maintain its infrastructure for the safety of the travelling public. While Maine DOT concedes that these will not provide the greatest benefits to overall stream health, they are vast improvements to improving habitat connectivity for many resident fish species, providing successful upstream passage that allows upstream habitat to be once again accessible for a variety of life stages throughout Maine. Several structure types are discussed here, including a sliplined culvert with weirs in Belfast and composite-invertlined multi-plate structures with weirs in Amherst and Ebeemee Township. As with all success stories, there have been failures along the way, but Maine DOT continues to improve on its passage techniques by learning from its mistakes. Passage strategies that did not go quite as planned will be discussed, including an early invertline attempt incorporating fish passage in Blue Hill, a slipline project with weirs in Johnson Mountain Township, and an invertlined multi-plate culvert with weirs in Canton.
