Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies of the Fund:
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund seeks to achieve its investment objectives by investing primarily in a diversified portfolio of common stocks, which Fund management believes offers the potential for increased earnings and dividends over time. Normally, such equity securities will represent 60% or more of the Fund's net assets. The equity investment approach of Bridges Investment Management, Inc. ("BIM" or the "Adviser") emphasizes owning companies in the Fund which it believes offer the best potential for above-average, long-term capital appreciation. The Adviser's equity investment process focuses on identifying companies which have accelerating revenues, earnings growth, strong dividend growth potential, free cash flow growth, expanding margins and strong balance sheets. Market capitalization or company size is a result of this investment approach rather than an active investment consideration. Historically, the Fund has primarily owned securities in larger companies, although at any time, the Fund may own securities in small, medium, or large size companies. The Fund may also invest in common stocks which the Adviser believes may be cyclically depressed or undervalued, and therefore, may offer potential for capital appreciation. In pursuing these principal investment objectives, the Fund may invest up to 15% of its total assets in U.S. dollar-denominated securities of foreign issuers traded on U.S. exchanges, and up to 20% of its total assets in American Depositary Receipts ("ADRs") traded on U.S. exchanges or in the U.S. over-the-counter market. In addition, to generate current income, as part of its principal strategy, the Fund may acquire investment grade corporate bonds, debentures, U.S. Treasury bonds and notes, and preferred stocks. Historically, such fixed income securities have not constituted more than 40% of the market value of the Fund's portfolio. Two considerations drive the Adviser's maturity strategy with respect to fixed income securities. First, the Adviser will generally manage the weighted average life of the Fund's fixed income portfolio given its perception of where value lies at any point in time on the yield curve. Second, the Adviser will manage the weighted average life of the Fund's fixed income portfolio based on its intermediate to longer-term outlook for interest rates at any point in time. The allocation of Fund investments among common stocks and other equity securities and bonds and other debt securities (including U.S. Treasury securities) is based on the Adviser's judgments about the potential returns and risks of each class. The Adviser considers a number of factors when making these allocations, including economic conditions and monetary factors, inflation and interest levels and trends, and fundamental factors (such as price/earnings ratios or growth rates) of individual companies in which the Fund invests.
Risk, Heading	rr_RiskHeading	Principal Risks of Investing in the Fund:
Risk, Narrative	rr_RiskNarrativeTextBlock	The risks associated with an investment in the Fund can increase during times of significant market volatility. There is the risk that you could lose all or a portion of your money on your investment in the Fund. The following risks could affect the value of your investment: Market Risk: The prices of the stocks in which the Fund invests may decline for a number of reasons such as changing economic, political or market conditions. The price declines may be steep, sudden and/or prolonged. Interest Rate Risk: The market value of bonds and other debt securities generally declines when interest rates rise. This risk is greater for bonds with longer maturities. Credit Risk: The risk of investments in bonds and debt securities whose issuers may not able to make interest and principal payments. In turn, issuers' inability to make payments may lower the credit quality of the security and lead to greater volatility in the price of the security. Asset Allocation Risk: The risk that asset allocation to a particular strategy does not reflect actual market movement or the effect of economic conditions. The Fund's performance may be affected by the Adviser's ability to anticipate correctly the relative potential returns and risks of the types of assets in which the Fund invests. Small and Medium Capitalization Risk: Investing in securities of small and medium capitalization companies may involve greater volatility than investing in larger and more established companies because small and medium capitalization companies can be subject to more abrupt or erratic share price changes than larger, more established companies. Foreign Securities and ADR Risk: Investing in foreign issuer securities and ADRs may involve risks in addition to the risks in domestic investments, including less regulatory oversight and less publicly-available information, less stable governments and economies, and non-uniform accounting, auditing and financial reporting standards.

SUMMARY SECTION

Investment Objective:

Bridges Investment Fund, Inc. (the "Fund") seeks long-term capital appreciation,

with a secondary objective of generating a modest amount of current
income.

Fees and Expenses of the Fund:

This table describes the fees and expenses that you may pay if you buy and
hold shares of the Fund:

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	Bridges Investment Fund, Inc.
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	none
Maximum Deferred Sales Charge (Load) on Reinvested Dividends and other Distributions	none
Redemption Fee (as a percentage of amount redeemed)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Bridges Investment Fund, Inc.
Management Fees		0.50%
Distribution (12b-1) Fees		none
Other Expenses	[1]	0.39%
Total Annual Fund Operating Expenses	[1]	0.89%

Example:

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of these periods. The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
Bridges Investment Fund, Inc.	91	284	493	1,096

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate
may indicate higher transaction costs and may result in higher taxes when
Fund shares are held in a taxable account. These costs, which are not
reflected in annual fund operating expenses or in the example, affect the
Fund's performance. During the most recent fiscal year, the Fund's
portfolio turnover rate was 26.6% of the average value of its portfolio.

Principal Investment Strategies of the Fund:

The Fund seeks to achieve its investment objectives by investing
primarily in a diversified portfolio of common stocks, which Fund
management believes offers the potential for increased earnings
and dividends over time. Normally, such equity securities will
represent 60% or more of the Fund's net assets.

The equity investment approach of Bridges Investment Management, Inc.
("BIM" or the "Adviser") emphasizes owning companies in the Fund which it
believes offer the best potential for above-average, long-term capital
appreciation. The Adviser's equity investment process focuses on identifying
companies which have accelerating revenues, earnings growth, strong dividend
growth potential, free cash flow growth, expanding margins and strong balance
sheets. Market capitalization or company size is a result of this investment
approach rather than an active investment consideration. Historically, the Fund
has primarily owned securities in larger companies, although at any time,
the Fund may own securities in small, medium, or large size companies.
The Fund may also invest in common stocks which the Adviser believes
may be cyclically depressed or undervalued, and therefore, may offer
potential for capital appreciation.

In pursuing these principal investment objectives, the Fund may invest up to 15%
of its total assets in U.S. dollar-denominated securities of foreign issuers
traded on U.S. exchanges, and up to 20% of its total assets in American
Depositary Receipts ("ADRs") traded on U.S. exchanges or in the U.S.
over-the-counter market.

In addition, to generate current income, as part of its principal strategy,
the Fund may acquire investment grade corporate bonds, debentures,
U.S. Treasury bonds and notes, and preferred stocks. Historically,
such fixed income securities have not constituted more than 40% of the
market value of the Fund's portfolio. Two considerations drive the Adviser's
maturity strategy with respect to fixed income securities. First, the Adviser
will generally manage the weighted average life of the Fund's fixed income
portfolio given its perception of where value lies at any point in time on the
yield curve. Second, the Adviser will manage the weighted average life of
the Fund's fixed income portfolio based on its intermediate to longer-term
outlook for interest rates at any point in time.

The allocation of Fund investments among common stocks and other equity
securities and bonds and other debt securities (including U.S. Treasury
securities) is based on the Adviser's judgments about the potential returns and
risks of each class. The Adviser considers a number of factors when making these
allocations, including economic conditions and monetary factors, inflation and
interest levels and trends, and fundamental factors (such as price/earnings
ratios or growth rates) of individual companies in which the Fund invests.

Principal Risks of Investing in the Fund:

The risks associated with an investment in the Fund can increase during
times of significant market volatility. There is the risk that you could
lose all or a portion of your money on your investment in the Fund.
The following risks could affect the value of your investment:

Market Risk: The prices of the stocks in which the Fund invests may decline
for a number of reasons such as changing economic, political or market
conditions. The price declines may be steep, sudden and/or prolonged.

Interest Rate Risk: The market value of bonds and other debt securities
generally declines when interest rates rise. This risk is greater for bonds
with longer maturities.

Credit Risk: The risk of investments in bonds and debt securities whose
issuers may not able to make interest and principal payments. In turn,
issuers' inability to make payments may lower the credit quality of the
security and lead to greater volatility in the price of the security.

Asset Allocation Risk: The risk that asset allocation to a particular
strategy does not reflect actual market movement or the effect of economic
conditions. The Fund's performance may be affected by the Adviser's ability
to anticipate correctly the relative potential returns and risks of the
types of assets in which the Fund invests.

Small and Medium Capitalization Risk: Investing in securities of small and
medium capitalization companies may involve greater volatility than investing
in larger and more established companies because small and medium capitalization
companies can be subject to more abrupt or erratic share price changes than
larger, more established companies.

Foreign Securities and ADR Risk: Investing in foreign issuer securities and
ADRs may involve risks in addition to the risks in domestic investments,
including less regulatory oversight and less publicly-available information,
less stable governments and economies, and non-uniform accounting, auditing
and financial reporting standards.

Performance:

The following bar chart and table provide some indication of the risks of
investing in the Fund by showing changes in the Fund's performance from
year to year and how the Fund's average annual returns over time compare
with those of a broad measure of market performance, as well as indices
that reflect the market sectors in which the Fund invests. The Fund's past
performance (before and after taxes) is not necessarily an indication of how
the Fund will perform in the future.

Total Return for the Calendar Years Ended December 31

The Fund's highest and lowest returns for a calendar quarter during the 10 year
period shown on the bar chart are a return of 21.26% for the quarter ended June
30, 2003, and -23.33% for the quarter ended December 31, 2008.

After-tax returns are calculated using the historical highest individual federal
marginal income tax rates and do not reflect the impact of state and local
taxes. Actual after-tax returns depend on an investor's tax situation and may
differ from those shown, and after-tax returns shown are not relevant to
investors who hold their Fund shares through tax-deferred arrangements, such as
401(k) plans or individual retirement accounts ("IRAs"). In certain cases, the
"Return After Taxes on Distributions and Sale of Fund Shares" may be higher than
other return figures. A higher after-tax return results when a capital loss
occurs upon redemption and provides an assumed tax deduction that benefits the
investor.
