As the length of the road network is increasing, appropriate choice of methods to preserve this investment becomes increasingly important. In the Ethiopian Roads Authority ERA published road design manuals to provide a standardized approach for the design, construction and maintenance of roads in the country. Due to technological development and change, these manuals require periodic updating and expanding. The new series of manuals has particular reference to the prevailing conditions in Ethiopia and reflects the experience gained through activities within the road sector during the last 10 years.

The updating of existing manuals and preparation of new manuals was undertaken in close consultation with the federal and regional roads authorities and stakeholders in the road sector. Most importantly, a series of thematic peer review panels was established that comprised local experts from the public and private sector who provided guidance and review for the project team.

The standards set out shall be adhered to unless otherwise directed by ERA. However, I should emphasize that careful consideration to sound engineering practice shall be observed in the use of the manual, and under no circumstances shall the manual waive professional judgment in applied engineering.

I would also like to extend my gratitude and appreciation to all of the industry stakeholders and participants who contributed their time, knowledge and effort during the development of the documents.

Special thanks are extended to the members of the various Peer Review Panels, whose active support and involvement guided the authors of the manual and the process. It is my sincere hope that this manual will provide all users with a standard reference and a ready source of good practice for the geotechnical design of roads, and will assist in a cost effective operation, and environmentally sustainable development of our road network.

I look forward to the practices contained in this manual being quickly adopted into our operations, thereby making a sustainable contribution to the improved infrastructure of our country.

Comments and suggestions on all aspects from any concerned body, group or individual as feedback during its implementation is expected and will be highly appreciated. The series describes current and recommended practice and sets out the national standards for roads and bridges.

The documents are based on national experience and international practice and are approved by the Director General of the Ethiopian Roads Authority. The complete series of documents, covering all roads and bridges in Ethiopia, is as follows: 1.

Route Selection Manual 2. Site Investigation Manual 3. Geotechnical Design Manual 4. Geometric Design Manual 5. Drainage Design Manual 9.

The route was planned, the hotel reservations were made, we had books and maps sent to us and we were provided with a phone and GPS.

Working with Alexandra was just a pleasure. From the very first email I sent of inquiry about the possibility of booking a trip with Nordic Visitor until the email I sent at the end of our trip asking if we could change our shuttle pickup time at the hotel, she was helpful, knowledgeable, responsive and always cheerful.

Thanks to Alexandra and Nordic Visitor, this was one of the best planned and organized trips we have ever taken. Nothing went wrong, but I have every confidence that Nordic Visitor would have helped us had there been any problems. I have no recommendations for how Nordic Visitor could improve what it does and that is unusual for me.

My expectations are high, and they were surpassed. Our trip to Iceland was unforgettable. Everything from the accommodations, to the rental car, to the travel documents exceeded our expectations.

Jelena was fabulous and truly put our minds at ease answering any and all questions. We were blown away by the beauty of Iceland and the incredibly warm people. Everything was incredible, and we can't wait to return. It was a thoroughly-planned trip from A to Z with many options to select from and add to the trip depending on the location.

The booklets given were most helpful and actually more efficient than Google, or just easier to navigate. Our hotels were perfect. We enjoyed wonderful dinners, some in the hotels, and others along the way. We were pleasantly surprised that even the smallest hotels served gourmet meals, great food and beautiful presentation. This was the vacation of our dreams and we were blessed to travel with our daughter and two granddaughters, ages 8 and 11. We were still in Iceland when the granddaughters talked of "when we come back to Iceland".

We then knew the trip was a success and we can't thank Gudrun and Nordic Visitor enough. All aspects of the trip exceeded my expectations and the service from first contact to arriving home was excellent. Thanks for the hard work that you put in and the variety of accommodation was just what was required. A truly memorable stay in Iceland which I hope to repeat soon. The location of hotels so close to trains was excellent.

Particularly liked the lovely new hotel in Trondheim and the interesting historic hotel in Bergen. Bjarni was available to answer our questions promptly while on the tour and arranged for our luggage transfer after the tour had started. I travelled with family to Denmark, Norway and Sweden this month and had a fantastic time, thanks in large part to the excellent job that Nordic Visitor did in coordinating my trip.

I customized one of their Scandinavian package deals by extending my time in certain cities and Nordic Visitor accommodated my requests. The hotels that they booked were very nice and all were close to tourist attractions and public transportation. The agency also booked some of the transportation, including a flight from Bergen to Stockholm, as well as all transportation for the Norway in a Nutshell tour, which was an awesome experience and the perfect way to take in the breathtaking scenery of the Norwegian mountains and fjords.

I would definitely use Nordic Visitor again, if I ever decide to return to Scandinavia. My wife and I took the Iceland Full Circle self-drive tour in early June.

We then stayed on in Reykjavik for a few days. Our tour was arranged by Jelena. She was very helpful.Having a car and a place to stay looked after made it very easy and flexible for us. We loved all the places booked for us. It was fantastic they offered breakfast for us. We would definitely use your services again some day and recommend to anyone considering a relaxing self drive vacation in Iceland.

The roads in Iceland were far better than I had envisioned. Cheers, Singer, The entire experience was fabulous. Having everything organized and written out by day was great. Each day was fantastic. Providing the GPS coordinates was brilliant. Our trip was made so easy because everything was beautifully organized for us. It was a fabulous experience. Each of the destinations was magnificent and we also did many of the suggested additional recommendations.

We would not have seen as much without the tour. Also, the hotel arrangements were terrific, and the voucher system made checking in very easy. We will be back. We simply loved our journey. The only thing is the cost of living and the exchange value of our canadian dollar.

But we were aware of this. Sofia made a perfect job to customize the tour and it the communications were easy and fast.

Thank you very much Sofia. We were able to see the midnight sun because of nordic visitor they have planned our tour very well and the local guides were very co operative. We used Larus at Nordic Visitors to arrange a weeklong tour of Reykjavik and the Southern Coast of Iceland.

We were extremely impressed with the quality of the services--and we have traveled extensively throughout the world. Larus was extremely responsive to our inquiries and tailored the perfect trip for us that allowed us to enjoy the country's beautiful scenery and to do a lot of great hiking. The travel plans were flawless--from the transfer at the airport, to the rental car and to the charming hotels he booked for us.

In fact, he even recommended stops along our itinerary for homemade ice cream. We would definitely use Nordic Visitor again for another trip to Iceland. We took their 17 day Grand Tour of Iceland. And they took care of our every want and need. From pre-planning to the last day of our visit, Nordic Visitor provided all of the assistance we needed.

There is no other way to see the entire country and travel in the style to which you are accustomed. We stayed in the best hotels around the Island.
