The following information replaces the second paragraph under the heading "Selling Shares" found in the "Buying and Selling Shares" section on page 17.

Spartan Arizona Municipal Income will deduct a short-term trading fee of 0.50% from the redemption amount if you sell your shares after holding them less than 30 days. This fee is paid to the fund rather than Fidelity, and is designed to offset the brokerage commissions, market impact, and other costs associated with fluctuations in fund asset levels and cash flow caused by short-term shareholder trading.

The following information replaces similar information under the heading "Policies" found in the "Account Features and Policies" section on page 24.

Fidelity may deduct an annual maintenance fee of $12.00 from accounts with a value of less than $2,000. It is expected that accounts will be valued on the second Friday in November of each calendar year. Accounts opened after September 30 will not be subject to the fee for that calendar year. The fee, which is payable to Fidelity, is designed to offset in part the relatively higher costs of servicing smaller accounts. This fee will not be deducted from accounts opened after January 1 of that calendar year if those accounts use regular investment plans.

SUPPLEMENT TO THE

SPARTAN^® SHORT-INTERMEDIATE MUNICIPAL INCOME FUND

October 23, 2000

STATEMENT OF ADDITIONAL INFORMATION

The following information replaces the similar information found under the heading "Yield Calculations" in the "Performance" section beginning on page 11.

Yield Calculations. Yields for the fund are computed by dividing the fund's interest and income for a given 30-day or one-month period, net of expenses, by the average number of shares entitled to receive distributions during the period, dividing this figure by the fund's NAV at the end of the period, and annualizing the result (assuming compounding of income) in order to arrive at an annual percentage rate. Yields do not reflect the fund's short-term trading fee, applicable to share purchased after April 16, 2001 that are held for less than 30 days. Income is calculated for purposes of yield quotations in accordance with standardized methods applicable to all stock and bond funds. In general, interest income is reduced with respect to bonds trading at a premium over their par value by subtracting a portion of the premium from income on a daily basis, and is increased with respect to bonds trading at a discount by adding a portion of the discount to daily income. Capital gains and losses generally are excluded from the calculation.

The following information replaces the similar information found under the heading "Return Calculations" in the "Performance" section beginning on page 11.

In addition to average annual returns, the fund may quote unaveraged or cumulative returns reflecting the simple change in value of an investment over a stated period. Average annual and cumulative returns may be quoted as a percentage or as a dollar amount, and may be calculated for a single investment, a series of investments, or a series of redemptions, over any time period. Returns may be broken down into their components of income and capital (including capital gains and changes in share price) to illustrate the relationship of these factors and their contributions to return. Returns may be quoted on a before-tax or after-tax basis. After-tax returns reflect the return of a hypothetical account after payment of federal and/or state taxes using assumed tax rates. After-tax returns may assume that taxes are paid at the time of distribution or once a year or are paid in cash or by selling shares, that shares are held through the entire period, sold on the last day of the period, or sold at a future date, and distributions are reinvested or paid in cash. Returns may or may not include the effect of the fund's short-term trading fee or the effect of the fund's small account fee. Excluding the fund's short-term trading fee or small account fee from a return calculation produces a higher return figure. Returns and other performance information may be quoted numerically or in a table, graph, or similar illustration.

The following information replaces the first paragraph following the heading "Historical Fund Results" in the "Performance" section on page 13.

Historical Fund Results. The following table shows the fund's yield, tax-equivalent yield, and returns for the fiscal period ended August 31, 2000.

Returns do not include the effect of the fund's 0.50% short-term trading fee, applicable to shares purchased after April 16, 2001 that are held for less than 30 days.

The following information replaces the similar information found in the"Performance" section on page 14.

Explanatory Notes: With an initial investment of $10,000 in the fund on September 1, 1990 the net amount invested in fund shares was $10,000. The cost of the initial investment ($10,000) together with the aggregate cost of reinvested dividends and capital gain distributions for the period covered (their cash value at the time they were reinvested) amounted to $16,003. If distributions had not been reinvested, the amount of distributions earned from the fund over time would have been smaller, and cash payments for the period would have amounted to $ 4,734 for dividends and $ 14 for capital gain distributions. The figures in the table do not include the effect of the fund's 0.50% short-term trading fee, applicable to shares purchased after April 16, 2001 that are held for less than 30 days.
