Laravel Route not working. Did not get The id

I have now working on a project called Hospital & Doctor Information. Here I have different Division in Bangladesh & in each division there are districts in which there are certain types of hospital according to their ownership. But when I get the value of different hospital from it shows me some error.It did not find the specific id. My route file

Route::get('/district/{id}', array('as' =>'district' ,'uses' => 'UserController@district'));

Route::get('/district/hospital/{id}', array('as' =>'hospital' ,'uses' => 'UserController@hospital'));

Route::get('/district/hospital/hospital_info/{id}', array('as' =>'hospital_info' ,'uses' => 'UserController@hospital_info'));

My Hospital Info Blade file is

<?php $active="hospital"; ?>
@extends('layouts.dashboard')
@section('content') 

    <section id="blog" class="container">
        <div class="center">
            <h2>Hospital Information</h2>
            <h3 class="lead">The government approved a renowned hospital and improved quality of service address , doctor , patient viewing time, bed , pathological tests in various subjects including costs and find the information here .<br> The bed and cabin bookings online , pathological tests , the doctor can be a serial for the meeting from the app .</h3>
