The first stable bridge over Lake Quinsigamond (the fourth such attempt overall) was an earthen causeway, finished in 1863. Formed from a mixture of rock, gravel and dirt, the causeway was the first span to not sway under heavy loads. The causeway effectively split the lake in half, stifling the nascent lakeside steamboat industry. Contemporary public opinion likened the causeway to an 'eyesore' and an 'abomination'. Despite these problems, the span survived into the early 20th century, when it was replaced by the current bridge. In ca. 1900, the causeway was expanded to include trolley tracks, linking downtown Worcester to the lakeside attractions.
