West Lebanon — Officials from Lebanon and Hartford are slated to gather this morning with history buffs and other community members to celebrate the dedication of the latest iteration of the Lyman Bridge.

The bridge carrying Route 4 across the Connecticut River between West Lebanon and White River Junction is being named to honor the legacy of Elias Lyman and his successors. Elias Lyman built the first toll bridge there in 1804. Various spans since then have been known as the Lyman Bridge, including a covered toll bridge built in 1835. Lyman was a merchant who also operated a cotton mill in Hartford.

The current Route 4 bridge, which opened in 2015, was built for $10.7 million and carries about 13,000 vehicles a day.

This morning’s celebration will take place at 10 a.m. on the New Hampshire side of the bridge.
