An oversight could’ve led to the Coupeville missing out on more than $100,000 in grant funds to complete a long-awaited project.

Construction of a section of sidewalk on Alexander Street is slated to begin this summer, but the project was accidentally left off the town’s six-year transportation plan.

To be eligible for Transportation Improvement Board grant money, it must be part of the plan.

Mayor Molly Hughes told town council members Tuesday night she can’t finalize the contract until the plan was revised. Following a public hearing, members passed a resolution fixing the error.

The sidewalk will be installed on Alexander Street in an area perpendicular to Coveland Street. People would illegally park cars in the spot, forcing pedestrians to either walk into the busy street or onto nearby private property.

The state-funded Transpor-tation Improvement Program also awarded the town more than $620,900 for improvements to South Main Street.

The project is also set to begin in the summer.
