Have you noticed the extra space on the Kampala Entebbe Expressway's curves compared to the straights? This is done for safety! It gives drivers better visibility around the bend, which is crucial for safely reacting in time and manoeuvring. Secondly, it allows for the reaction time limits, which is why the 100km/h speed limit is essential. You need almost two football pitches to be able to stop and react. Drive #safely.

Why is the paved section of the Kira-Kasangati-Matugga road smaller compared to the total width of the road under construction? To find out read below. (Detailed Video in Frame 4) The Kira-Kasangati-Matugga project aims to upgrade the entire road to paved standards, with a design that includes: (I) 3.5-meter lanes: Standard lane width for vehicular traffic. (II)1.5-meter shoulders: Provide safety margins and space for breakdowns. (III)4.0-meter green belt:Promotes environmental benefits and future lane expansion. (IV)2.0-meter cycle lane:Encourages eco-friendly transportation. (V)2.0-meter pedestrian walkway:Improves safety for non-motorized users. The cycle lane specifically aligns with promoting zero-emission transport and environmental benefits. While the paved section is still in progress, the road's width accommodates these planned features for a safer and more sustainable transportation infrastructure in the future. #UNRAworks

Let's talk about the Kampala-Entebbe Expressway. Why all the emphasis on "slow down on rainy days" signs? Is the Expressway suddenly an aquarium when it rains? Do the road designers need to include something on this fancy road? Could my second-hand tyres be a factor? Is this a unique issue in Uganda? Speaking of missing things, let's discuss aquaplaning or hydroplaning – not the cool Olympic sport, unfortunately. Aquaplaning (hydroplaning) happens when a layer of water builds between your tyres and the road, significantly reducing your ability to steer, brake, and control your vehicle. Here are factors making hydroplaning worse: 1.Speed demons:(aka Subaru drivers, please tag them): Some drive like Usain Bolt on a waterslide 🏎️💨 2.Bald tyres: If your treads resemble post-lockdown hair, it's time for new ones 😬 Treads help clear water. 3. Deep puddles: Great for hippos, not cars 🦛 Water takes time to clear in heavy rain. Uganda's love for second-hand tyres: Let's face it, those treads are often unreliable. New tyres should be changed every 6 to 10 years, while old ones should be changed every 1 to 3 years. The equation is simple: rain + speed + bad tyres = potential disaster. Want to play bumper cars? Go to an amusement park, not the Expressway. How to avoid hydroplaning on the Expressway: 1. Reduce Speed: Slowing down significantly improves tyre grip. Aim for 50 to 60 km/hr. 2. Maintain Tire Health: Ensure adequate tread depth for water displacement. 3. Increase the Following Distance: Allow more reaction time. 4. Focus and Visibility: Turn on headlights and stay alert. 5 Avoid hard braking and sharp turning. If you are hydroplaning, consumer reports experts recommend taking your foot off the gas, steering in the desired direction once traction is regained, and gently applying the brakes.

The Kampala Entebbe Expressway is now illuminated, with the Northern Bypass set to follow suit. Given its cost-effectiveness and low maintenance, some may wonder why solar lighting wasn't utilized. The first challenge is solar energy, which faces intermittent generation and varying sun hours in different regions. In Kampala, the average sun hours generating light is 3.5 to 4 lux, compared to 6 in Northern Uganda. Seasonal variations further impact consistency, making maintaining the recommended 40-70 lux lighting for expressways throughout the night challenging. This inconsistency poses safety concerns on high-speed roads. Second challenge Vandalism is another issue, as batteries used in solar lighting can be targeted for resale at 12Volts /24Volts. Despite efforts to deter vandalism, the challenge persists. Telecom towers, which also use solar, avoid this issue due to continuous monitoring, which can't be done for a road with 180 lights and less marketable 48Volt inverters. These things are hard to sell. The final Challenge is maintenance and durability. Uganda is a country of pollen, dust and grime. Regular checks on battery efficiency, cleaning of solar panels, and monitoring darkness sensors are essential in our dusty environment. Standard lighting may be simpler to maintain, focusing mainly on the bulb. While solar may be unavoidable in remote and hard-to-reach areas, the initial installation cost, inconsistent light output and maintenance challenges currently make grid power a more practical choice. While there have been successful solar implementations on a global scale, the widespread adoption of solar technology is still in its nascent stages. Notable examples include the A14 in England, where a section incorporates solar lighting, a 24km expressway in Chile that utilizes solar panels, and a segment of Interstate 10 in Arizona dedicated to illuminating wildlife crossings using solar power. These cases illustrate promising strides in integrating solar solutions, yet comprehensive deployment is yet to reach maturity. The transition to renewable energy is seen as inevitable, but for now, standard roads are better suited for solar lighting with manageable lux and duration requirements, e.g. Kira Matugga KCCA roads.

Remember Kampala's Clocktower in 2016? It was a total disaster when it rained! People were stranded, wading through flooded streets, trying to balance on those tiny medians to cross the road. But then came the Kampala Flyover Project! They didn't just build a flyover; they tackled the root of the problem: the drainage. First, they widened the St. Dennis channel. But then came the big challenge: the Clocktower junction! There was no space to enlarge the channel there. So what did they do? These brilliant engineers built the channel UNDER the Clocktower—a hidden waterway flowing from Pan African Square to the Nakivubo channel! Now, you can drive past the Clocktower on the rainiest day, and it's smooth sailing! No more floods, no more traffic jams. What a transformation! #UNRAworks
