rivers and harbors projects up to 1963, this amount may largely be 

 written off. In essence, this assumes the income effects of these expen- 

 ditures do not significantly add to the value of the port. On the other 

 hand, the much greater amount of investment in 1967, a $14.3 million 

 dredging project over a shorter period of time, will affect the economy 

 of the port community. Since this dredging is to enable the port to 

 handle the newer deeper draft vessels, it is necessary to prevent port 

 obsolescence. Again, using a 50-year straight-line depreciation an 

 average annual charge would amount to $268,000.

In addition to the commercial shipping aspects of transportation, 

 the impact of toll bridges must be considered. There are three toll 

 bridges, the Jamestown Bridge from North Kingston to Connecticut 

 Island, the Mount Hope Bridge from Bristol to Portsmouth, and the 

 Newport-Jamestown Bridge, which will replace the ferryboats. The 

 Jamestown Bridge will become toll free in 1969 when its bonds are 

 redeemed. The Mount Hope was built in 1929 and its outstanding 

 bonds were retired in 1964. Tolls will continue to be collected until 

 the Newport-Jamestown Bridge is paid off. The Newport-Jamestown 

 Bridge is scheduled to open in 1969. The bridge is being built at an 

 estimated cost of $60 million.

Marine-oriented industry and commerce 



A survey conducted in 1965-66 showed 75 marine-oriented firms lo- 

 cated around Narragansett Bay in addition to marinas and boatyards. 

 The firms are involved in such activities as ship and boat building, 

 marine electronics, sail making, and fishnet construction. At the time
