A narrowed set of hybrid scenarios for replacing the Alaskan Way Viaduct will be presented for comment at an open forum Dec. 15.

From the eight scenarios studied for the last six months, the most promising building blocks will be reassembled into two or three "hybrid" scenarios for evaluation, and for comment from the public, 5 to 7:30 p.m., Monday, Dec. 15 at Town Hall, 1119 Eighth Ave. Officials from the Seattle, King Count and Washington State departments of transportation will present the scenarios, answer questions and take comments.

Before the end of the year, they will be recommending a single solution to the mayor, the county executive and the governor.
