BANGOR, Maine — Having trouble wrapping your head around what a diverging diamond interchange is? These videos might help clear it up.

The Maine Department of Transportation created a series of short clips to help people get a first-person perspective of what driving through the interchange would be like.

The state wants to build the interchange, which would be the first of its kind in the state, on the Hogan Road bridge that passes over Interstate 95. MDOT officials are concerned with the high rate of crashes in that area, traffic backups and the dangerous conditions for pedestrians and bicyclists. The only way of solving those problems without great expense is using this design, MDOT argues.

The project is still in conceptual stages, and hasn’t been fully planned. It likely won’t be completed until 2018 or 2019, unless MDOT hears strong public support for the project and decides to fund it earlier. It’s expected to cost between $3 million and $5 million.

Public hearings are expected to be scheduled in the future as the project enters design stages. The concept received solid support from a small group of residents and city officials during an informational meeting Thursday night.
