The second bridge (Bridge 16) by Jefron Gaw, Allan Mariano and Lex Alviar was withdrawn from the competition because its depth D exceeds the limit, making it impossible to test the bridge using two point loads. The bridge has an arch shape. The bridge is quite heavy W=1425 g. It is a well designed bridge and it may have performed well in the competition, if it only passed the specifications. The bridge was actually tested upto failure using the UTM and observe the failure mode - a bending failure at midspan.

In the recently concluded 5th DLSU-CES Bridge Building Competition last 7 Feb 2009, the bridges made from popsicle sticks competed for the Best Bridge Design based on the following criteria:
- Creativity and Innovativeness in the design and form: 30%
- Application of bridge design principles: 30%
- Practicality and implementability: 20%
- Neat and well-polished bridge: 20%
Four judges examined and evaluated the bridges. After about an hour of evluation, the scores were tabulated. It was a tight race for the winner. The winning bridge from Don Honorio Ventura College of Arts and Trades (DHVCAT) won by a hairline against the bridge entry from the Technological Institute of the Philippines (TIP), Manila. The 3rd placer is the bridge from the Technological Institute of the Philippines (TIP), Quezon City. Building popsicle-stick bridges using glue takes a lot of planning, patience and ingenuity. Cutting the popsicle sticks to fit the form of the bridge, gluing the sticks and polishing involves a lot of time. In general, the popsicle-stick bridges submitted were impressive. Many of the bridges were unique and may serve as models for future bridges. The students have demonstrated their skills and understanding about bridge construction.
