Construction has already begun on a half-million dollar underpass to relieve traffic congestion at the intersection of soldiers Field Road and the Larz Anderson bridge. The entire project will probably be competed by October, according to Edward McSweeny, senior civil engineer for the Boston Metropolitan Commission.

Meanwhile, the Commission is dewing up plans either to shuttle traffic onto Memorial drive or another road running parallel to Soldiers Field Road. Sale roads, with traffic lights, will also be constructed for traffic turning off Soldiers Field Road onto Harvard St.

As the first step, road crews have taken down all the trees in the area of the intersection.
