The State Bond Commission is expected to approve nearly $90 million in bonds to begin construction on a planned busway between New Britain and Hartford.
The panel, chaired by Gov. Dannel P. Malloy, is scheduled to vote today on the project.
Malloy announced this month that he was backing the project, estimated to cost more than $572 million. He said he was reluctant to risk losing federal funding for the paved, 9.4-mile corridor.
The federal government is expected to spend nearly $460 million on the project. Connecticut has already spent more than $23 million on design and acquiring property.
Proponents say the busway, to run along unused rail lines through New Britain, Newington, West Hartford and Hartford, will relieve traffic congestion along Interstate-84. Construction is expected to begin this summer.
