Unprecedented use of prefabricated and previously used materials simplified construction and minimized costs, and much of the outdoor work was completed under poor weather conditions.

The popularity of Eggemoggin Reach as a yachting area called for a 200-foot-wide (61 m) channel at midspan with a minimum 85-foot (26 m) under clearance, placing the roadway at 98.7 feet (30.1 m) above mean water level.

The project was also complicated by its required early-summer completion date, meaning that much of the work had to be done during the winter and early spring months when weather conditions posed a significant challenge.

Robinson and Steinman and their contractors solved this difficulty by prefabricating many of the components offsite and completing the bulk of the assembly quickly, working between high tides.

After mud was removed from the bottom and the rock foundation carefully sounded, the dam bases were torch-cut to fit the profile of the irregular bedrock on which they were to be set.

On the superstructure, pre-stressed twisted-strand cables invented by the designer were used to advantage on both the main strands and the suspenders, meaning the time-consuming and expensive field adjustments were unnecessary.

These connections, invented by Robinson and first used on the Thousand Islands Bridge the previous year, made small adjustments to the main strands very easy.
