The State Bond Commission has approved nearly $90 million in bonds to begin construction on a planned busway between New Britain and Hartford, The Associated Press reports.
The vote came despite concerns raised by Republican members about the project's high price tag.
The panel, chaired by Democratic Gov. Dannel P. Malloy, met Friday to approve Connecticut's share of the construction costs.
Malloy recently announced his support for 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 busway. Connecticut has already spent more than $23 million on design and acquiring property.
Proponents say the busway will relieve traffic congestion along Interstate-84. Construction is expected to begin this summer.
