Daftar ini belum tentu lengkap. Anda dapat membantu Wikipedia dengan mengembangkannya.

Jaringan Nasional (atau Jaringan Truk Nasional ) adalah jaringan jalan raya negara bagian dan antarnegara bagian yang disetujui untuk pengemudi truk komersial di Amerika Serikat . Undang -Undang Bantuan Transportasi Permukaan tahun 1982 mengizinkan pembentukan jaringan jalan raya nasional yang ditujukan untuk digunakan oleh truk- truk besar . Di jalan raya ini, batas lebar dan panjang Federal berlaku. Jaringan Nasional (NN) mencakup hampir semua Sistem Jalan Raya Antar Negara Bagian dan jalan raya non-Antarnegara bagian lainnya yang ditentukan. Jaringan ini terdiri dari lebih dari 200.000 mil (320.000 km) jalan raya.^[1]

658.9 Kriteria Jaringan Nasional Jaringan Nasional yang tercantum dalam lampiran bagian ini tersedia untuk digunakan oleh kendaraan bermotor komersial dengan dimensi dan konfigurasi yang dijelaskan dalam 658.13 dan 658.15. Untuk negara-negara bagian dengan daftar rinci rute individu dalam lampiran, rute telah ditetapkan berdasarkan kepatuhan umum mereka terhadap kriteria berikut.

• Rute tersebut merupakan komponen khas geometris dari Sistem Primer Bantuan Federal, yang menghubungkan kota-kota utama dan bagian-bagian negara bagian yang berkembang pesat.
• Rute tersebut merupakan rute volume tinggi yang digunakan secara luas oleh kendaraan besar untuk perdagangan antarnegara bagian.
• Rute tidak memiliki batasan yang menghalangi penggunaan oleh kendaraan kombinasi konvensional.
• Rute tersebut memiliki geometrik yang memadai untuk mendukung operasi yang aman, dengan mempertimbangkan jarak pandang, keparahan dan panjang kemiringan , lebar perkerasan, kelengkungan horizontal , lebar bahu , jarak bebas jembatan dan batas beban, volume lalu lintas dan campuran kendaraan, dan geometri persimpangan.
• Rute terdiri dari jalur yang dirancang dengan lebar 12 kaki (3,66 m) atau lebih atau konsisten dengan keselamatan jalan raya.
• Rute tidak memiliki karakteristik yang tidak biasa yang menyebabkan masalah keselamatan saat ini atau yang diantisipasi.

Jaringan Nasional baru - baru ini ditetapkan oleh Undang - Undang Efisiensi Transportasi Permukaan Antar moda tahun 1991 . Informasi tentang rute ini diambil dari 658 Lampiran A. Beberapa negara bagian seperti Indiana , Arkansas , dan Ohio mengizinkan lalu lintas truk di semua jalan raya negara bagian atau AS bernomor . Negara bagian lain, seperti New York dan California , memiliki seperangkat jalan raya yang ditentukan secara khusus yang direkomendasikan untuk truk. Undang-undang mengizinkan "akses yang wajar" ke dan dari NN untuk terminal, pengiriman, pemberhentian truk, perbaikan, dan alasan lainnya. NN direkomendasikan untukmelalui lalu lintas truk (misalnya lalu lintas yang melewati area tersebut), dan truk diizinkan beroperasi di jalan yang dibatasi truk jika tidak ada sarana akses lain ke tempat tujuan.^[1]

Note: US 23 crosses the Ohio River between South Shore, KY and Portsmouth, OH via the U.S. Grant Bridge. Although the state line is near the Ohio shoreline, putting most of the bridge in Kentucky, the terminal point for US 23 is listed as the south end of the bridge because the bridge is maintained by the Ohio DOT.
