Interstate 93 Transit Investment Study
Southern and Central New Hampshire, the I-93 Corridor, has developed rapidly during the past several decades, emerging from a pastoral rural setting to become an area of bedroom communities for the metropolitan regions of Boston, Manchester and Nashua. 
In fact, several communities in the corridor have developed economic bases of their own, further increasing pressure on the transportation infrastructure. This growth has led to increased concerns for safety and efficacy of the overall transportation system, and to plans to expand capacity. As part of that effort in June 2004 NHDOT released a Final Environmental Impact Statement (FEIS). That document includes a recommendation to widen I-93 from two lanes to four lanes in each direction. NHDOT is now moving to implement that recommendation. In a complementary effort, NHDOT is now undertaking a study to evaluate the feasibility of alternative transportation modes and corridors in the I-93 corridor between Boston and Manchester.
