The State Bond Commission on Wednesday approved hundreds of millions of dollars in new financing to spur apartment and affordable housing developments in Hartford and other transportation-related improvements, among other allocations. The largest approval on Wednesday was a $135 million request from the Connecticut Department of Transportation for various resurfacing and reconstruction projects and road and bridge repairs. In Hartford, other borrowing requests approved included $13.5 million in loans for the creation of 155 apartment units downtown. The funds were requested by the quasi-public Capital Region Development Authority (CRDA). CRDA Executive Director Michael Freimuth responded by saying the financing was needed because many housing projects downtown lack any level of return on investment.
