Problem with Html.Partial and ViewBag

I have my following controller:

public ActionResult Index2(int Id= 0)
{
  if (Id == 0)
  {
    return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
  }
  ViewBag.ClienteId = Id;
  return View();
}
public ActionResult Index3(int Id= 0)
{
  if (Id == 0)
  {
    return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
  }
  ViewBag.ClienteId = Id;
  return View();
}

and others

In all of them, I have a partial with the following code:

        @Html.Partial("_MenuInfo")

And in it I have my menu with the Customer Id as I go through the ViewBags

<div class="col-md-12">
    <div class="row">
        <ul class="nav nav-tabs" role="tablist">
            <li class="active"><a href='@Url.Action("Novo", "Grupo", new { area = "Cadastro" })/@ViewBag.ClienteId' class="btn btn-success">Grupo</a></li>
            <li><a href='@Url.Action("Novo", "Acesso", new { area = "Cadastro" })/@ViewBag.ClienteId' class="btn btn-success">Acesso</a></li>
        </ul>
    </div>
</div>

But it happens that as I browse the links

He is rendering the following link

Group / New / 17/17

That is, you are generating 2x the Client code that comes from the ViewBag

I need this menu to be in several Views, so that when I give a "New" I already send the Client Id that is an FK in the table
