National Highway 505, commonly called NH 505, is a national highway in India.^[1] It is a spur road of National Highway 5.^[2] NH-505 traverses the state of Himachal Pradesh in India. NH505 a high elevation road, covers Kinnaur and Lahaul and Spiti districts of Himachal Pradesh, mainly running along Spiti river in Spiti valley. The highway from Kaza to Gramphu remains closed for 6–9 months in a year due to heavy snowfall and closure of Kunzum La pass at an elevation of 4,550 m (14,930 ft).^[3][4]

Overview[edit]

National Highway 505, was designated Himachal state highway 30 prior to its being notified on 4 March 2014 as a national highway.^[5] The highway runs through the high elevation cold desert area of Lahaul and Spiti valleys of Himachal, which area receives negligible rainfall.^[1] The terrain is barren and treacherous, prone to landslides and disruptions. The road is narrow and rough at places and crosses the high elevation Kunzum pass, requiring good driving skills in mountains.^[6]

NH 505 has been of key importance to the growth of a cash crop economy, mass tourism, and the expansion of telecommunications in Spiti.^[7] This highway provides connectivity to some major Buddhist monasteries and various other interesting places.^[8]

Route[edit]

The route of NH-505 starts at the Khab Sangam in Kinnaur district from National Highway 5. It runs along the Spiti valley through Kinnaur and enters Lahaul and Spiti district at Sumdo. It continues up the Spiti valley to Kunzum Pass. It descends and follows the Chandra River to the terminus at Gramphoo.^[1]

Kinnaur district[edit]

The terminus at Khab, Kinnaur district is the preferred point of entry to Spiti valley which is located at an average elevation of 3,350 m (10,990 ft).^[4] This mostly all-weather access point to Spiti valley from Khab is at an elevation of about 2,600 m (8,500 ft). Travelling from Chandigarh or Shimla to Khab gives a chance for travellers to gradually acclimatize themselves to avoid altitude sickness. NH-505 climbs steeply from Khab Sangam up to Nako (3,662 m (12,014 ft)). It descends to Chango on the Spiti River, then enters Lahaul and Spiti district at Sumdo.

Lahaul and Spiti district[edit]

From Sumdo, NH-505 runs mostly alongside the Spiti river for about 130 km (81 mi) until Losar. After passing through Hurling, the next town is Tabo with the well-known Tabo Monastery and caves. The highway passes through some unusual clay pillars^[10] en route to Kaza, the largest town in Spiti valley. Near Lingti, 15 km (9.3 mi) before Kaza, the 33 km (21 mi) road to Pin Valley National Park branches off over the Attargo Bridge to the right bank of the Spiti.^[11] On the Tabo side of Lingti is the road to the Dhanker Monastery. In this section, the riverbed is very wide, up to 500 m (1,600 ft) in places. The river itself is much narrower and meanders in braids along the broad riverbed.^[10]

After Kaza, NH-505 crosses to the right bank of the Spiti river over the Rangrik Bridge. At the bridge, the Kaza-Kibber road continues on the left bank to Key Monastery (8 km (5.0 mi)) and the Kibber Wildlife Sanctuary (15 km (9.3 mi)).^[12] NH-505 continues on the right bank running through a flat, narrow valley in which the Spiti river has carved a gorge about 300 m (980 ft) deep. The road crosses back to the left bank 3 km (1.9 mi) before Kialto village. Here, the Kaza-Kibber road rejoins NH-505, a distance of 22 km (14 mi) from Kibber. After Morang and Hanse villages, the valley broadens before Losar village.

After Losar, NH-505 turns up the right bank of the Lichu, a right bank tributary of the Spiti. The road climbs gradually up to Kunzum La, elev. 4,551 m (14,931 ft). There is a temple at the pass.

From Kunzum pass, the highway descends through steep hairpin bends to Batal village on the left bank of the Chandra river. Chandra Taal is a pristine lake on the Chandra River popular with tourists and high-altitude trekkers. The road to Chandra Taal branches off from NH-505 about 2.9 kilometres (1.8 mi) from Batal and 8 km (5.0 mi) from Kunzum Pass.^[13]

From Batal, NH-505 follows the left bank of the Chandra river, practically running on the riverbed in some places as both sides of the narrow valley are very steep. This section is largely unpaved and impassable during the winter months. Passing through Chotta Dara the highway reaches Chhatru where it crosses to the right bank. It climbs steeply and runs along the top of a cliff overlooking the Chandra river until the terminus at Gramphu (Gramphoo).^[5]
