Option 1

Option 1: The Bow [More]
Tower Height:	Approx. 130 metres above sea level
Main Span Length:	Approx. 200 metres
Capital Cost:	Lowest amongst the six options
Description:	The tower of a cable stayed bridge is its most noticeable and symbolic feature. The Bow has a unique curved tower penetrating through the deck structure which is evocative of an archery bow being pulled back, as if about to fire an arrow. The cables shooting forwards from the tower and the deck symbolising the arrow in flight is a dynamic concept which is consistent with the long term vision for Tseung Kwan O as a developing vibrant town on the move.

Option 2

Option 2: Link with Wings [More]
Tower Height:	Approx. 120 metres above sea level
Main Span Length:	Approx. 200 metres
Capital Cost:	5% (approx. HK$100M) higher than Option 1
Description:	This cable stayed bridge has a pair of outwardly leaning towers, which rise up like a bird outstretching its wings at Junk Bay. This concept has a symbolic connection with nature, and the slender towers give the bridge a sense of peace and tranquility. Greening and landscaping features that are proposed on the bridge deck for Cross bay Link are particularly in harmony with this theme, therefore bringing the two sides of Junk Bay together to offer Tseung Kwan O a real Link with Wings.

Option 3

Option 3: The Sail [More]
Tower Height:	Approx. 120 metres above sea level
Main Span Length:	Approx. 170 metres
Capital Cost:	10% (approx. HK$200M) higher than Option 1
Description:	The Sail appears like a two-mast junk on the horizon of Junk Bay thanks to the two sail-like towers of the cable stayed bridge. This maritime theme is consistent with the history of Junk Bay and the future plan for Tseung Kwan O coastal area as a destination location for water related activities. Unique to this option, the cycle/footway are on a separate structure, slightly offset, and below the main highway bridge. This separation allows pedestrians and cyclist to enjoy views along the route of Junk Bay, Lei Yue Mun and Tathong Channel.

Option 4

Option 4: Alliance Bridge [More]
Tower Height:	Approx. 60 metres above sea level
Main Span Length:	Approx. 160 metres
Capital Cost:	5% (approx. HK$100M) higher than Option 1
Description:	The four short pillar-like towers give the image of strength, which when coupled with the cables appear like four companions, linking hands to support the bridge. The concept of people linking hands symbolizes how by working together and through great friendships, residents can build Tseung Kwan O into a great place. The low profile nature of the towers, gives the Alliance Bridge its elegant and simple impression that appears as a seamless addition across the bay.

Option 5

Option 5: Eternity Arch [More]
Arch Height:	Approx. 70 metres above sea level
Main Span Length:	Approx. 200 metres
Capital Cost:	10% (approx. HK$200M) higher than Option 1
Description:	Two relatively low profile outwardly leaning arches are visually connected to carefully sculpted piers to create an eternal never-ending loop, like the one created by the cycle track loop around the shores of Junk Bay, which is completed by Cross Bay Link. The Eternity Arch leaps across the channel with an energetic movement frozen in time, which reinforces the concept of eternity. The use of a strong symbolic identity creates a landmark sculpture for the residents of Tseung Kwan O to enjoy and contemplate.

Option 6

Option 6: The Gateway [More]
Arch Height:	Approx. 110 metres above sea level
Main Span Length:	Approx. 200 metres
Capital Cost:	5% (approx. HK$100M) higher than Option 1
Description:	The single arch of The Gateway crosses the eastbound carriageway diagonally, thus creating a grand gateway to Junk Bay and Tseung Kwan O for both road users and boats entering the bay. The mountain shaped profile of the arch reinforces this sturdy gateway image and gives the bridge the sense that it is a harmonious continuation of the surrounding hillside. In addition, the split-box arch structure creates an interesting effect of light and shade.
