Actually they built an asphalt concrete road which connect Mile to Waldiya some time last year so I think it relieves the congesion on this road probably they rebuilt it since there are lots of industrial investment in Kombolcha city.Road 2 from Kombolcha to Mile
This road was probably also built during Italian occupation to connect Addis Abeba to port of Assab. This was main road to Assab until new road between Awash and Mile was built at some time during second half of 20th century. Currently it is main road from Djibouti to Northern Ethiopia (to many parts of Amhara and Tigray Regions). So it is quite a busy road for Ethiopian standards with lots of trucks carrying fuel and other goods from Djibouti.
They charge 50 Eth birr($2.50 USDollar) for small cars, medium size cars will pay 60 Eth birr($3.00 USDollar) and big cars 70 Eth birr ($3.50 USDollar) for the whole 76 Kilometers use (up to Adama) .
