miniace · June 22, 2012

Outer Circular Highway (OCH) to the City of Colombo is one of the expressways proposed. On completion, this highway will provide access to existing "A" class roads and proposed expressways at the interchanges, and as such will serve as the basis for the entire network of Highways and Expressways in the country.

Outer Circular Highway details are as given below.

Length: 28km

Design speed :80 Km/h

Lanes : Initially 4, Ultimate stage 6

Underpasses and overpasses have been proposed for the intersecting roads other than "A" Class roads. Provision of width of these underpasses has been made to satisfy Road Development Authority requirements for the class of road concerned. Frontage road of 6.0m wide on either side of the expressway will be provided wherever necessary to provide access to residents

Interchanges to the Outer Circular Highway have been proposed for "A" class roads and other expressways at the following locations.

Kerawalapitiya with Colombo - Katunayake Expressway
Mattumagala with Peliyagoda - Puttalam Road
Kadawatha (East of Kadawatha Town) with Colombo Kandy (A1) Road & proposed Colombo Kandy Expressway
West of Biyagama Town with Kelaniya - Mudungoda Road
West of Kaduwela Town with Colombo - Hanwella Low Level Road
Makumbura (East of Kottawa Town) with Colombo - Ratnapura - Wellawaya - Batticaloa (A4) Road and proposed Southern Expressway (E01)

More Aerial pictures will follow soon.

I think this mattumagala interchange would unnecessarily fill up the CKE tarffic volume.

OCH or its Interchange crossing the Kadawatha - Ganemulla Road within first 1km from Kadwatha side. RDA has been already marked and fixed yellow coloured new RDA posts there about 10 moths ago.

I think this only interchange to A3 is at Ja-Ela. If your facts are correct, it will serve the purpose for CKE, otherwise it will be another typical SL route. Mini's speed for OCH is correct, but for CKE it is 100 km/h.

Speed of OCH will be 100 km/hr same as present Southern Expressway. Please kindly accept the truth.

Hi Jdnet, no problems in having your view to yourself. But could you let know why you think Arthur C, is a not a worthy name or an individual.............

Davy · July 22, 2012

Thanks for the info + photos miniace.

OT: Let alone new roads, I seriously don't understand why they change existing names of roads like "Guildford Crescent" to names of individuals I haven't even heard of.

Great Basses. Shipwreck. Tons (literally) of silver plus a dozen or so cannons.

Donates a few pieces to Smithsonian. None to our local museums.

Pocketed the hefty bit of change from the rest.

He's a stereotypical suddha that stole the lands treasures while the Sinhalese praised him.

Oh yeah and please don't give me the speech about how he has given so much for this country. The fact is Clarke would be nothing if it weren't for this country.

Science fiction writers are a dime-a-dozen.

just wanted to know the facts and thoughts behind your comment. I always know that others may know something that I do not know........your points may be correct and personally I feel Dr Kulasinghe memorial Express Way is a fitting name for an iconic Civili Engineering project of the country.

By the way I cannot agree with "Science fiction writers are a dime-a-dozen"............I have read many and Arthur C is a damn good one of them.
