Use a RewriteRule. The RegEx pattern will match the path part of the URL request, and only the path part. The target of the Rule will be the new URL. Use a question mark to suppress parameters from being re-appended to the new URL. Add flags to force the 301 status and to make it the Last rule if the pattern matched.
You'll need a preceding RewriteCond. This will look at THE_REQUEST and match requests that include the path and parameter that you want to redirect.
It's a couple of lines of code, and there's many previous examples as this question comes up several times per month.
