asp.net mvc Html.ActionLink() keeping route value I don't want

I have the following ActionLink in my view

<%= Html.ActionLink("LinkText", "Action", "Controller"); %>

and it creates the following URL http://mywebsite.com/Controller/Action

Say I add an ID at the end like so: http://mywebsite.com/Controller/Action/53 and navigate to the page. On this page I have the markup I specified above. Now when I look at the URL it creates it looks like this:

http://mywebsite.com/Controller/Action/53 (notice the addition of the ID)

But I want it to remove the ID and look like it did originally, like this http://mywebsite.com/Controller/Action (notice no ID here)

Any ideas how I can fix this? I don't want to use hard coded URLs since my controller/actions may change.

The solution is to specify my own route values (the third parameter below)

<%= Html.ActionLink("LinkText", "Action", "Controller", 
    new { id=string.Empty }, null) %>

The problem is the built in methods take input from the URL you are currently on as well as what you supply. You could try this:

<%= Html.ActionLink("LinkText", "Action", "Controller", new { id = ""}) %>

That should manually wipe the id parameter.

Don't know why, but it didn't work for me (maybe because of Mvc2 RC). Created urlhelper method =>

 public static string
            WithoutRouteValues(this UrlHelper helper, ActionResult action,params string[] routeValues)
        {
            var rv = helper.RequestContext.RouteData.Values;
            var ignoredValues = rv.Where(x=>routeValues.Any(z => z == x.Key)).ToList();
            foreach (var ignoredValue in ignoredValues)
                rv.Remove(ignoredValue.Key);
            var res = helper.Action(action);
            foreach (var ignoredValue in ignoredValues)
                rv.Add(ignoredValue.Key, ignoredValue.Value);
            return res;
        }
