The Merrimack Valley TMA was founded as the River Road Transportation Management Association (RRTMA) in 1997. The TMA is a non-profit organization composed of employers and property owners who are working together to address employee transportation issues in the Merrimack Valley area of Andover and along the I-93 and I-495 corridors.
The River Road area and the neighboring communities of Haverhill, Lawrence, Methuen, and North Andover have seen an unprecedented amount of development over the past few years. This has resulted in a significant amount of traffic. As traffic congestion in the region continued to increase, the River Road TMA expanded to address related region-wide traffic issues in the communities of Lawrence, Methuen, North Andover and in 2010, the TMA expanded its service area to include Haverhill. The TMA has enhanced its role to serve as a resource for employers to comply with the Massachusetts Rideshare regulations, advocate for commuter-oriented and sustainability legislation, and serve as a forum for the exchange of information and ideas that impact economic development in the greater Andover region.
