Thanks, Doug, and good morning, everyone. We are pleased with our results at TDS Telecom for the second quarter and through the first half of the year, and we are tracking to our financial guidance expectations. We remain committed to our primary strategic objective to provide growth and improve returns by investing in our flagship product, high-speed broadband. We are directing our investments to expand our fiber footprint in new and existing markets and to enhance our product offerings. These investments are driving connection and revenue growth. This quarter, we added 17,000 marketable fiber service addresses to our footprint. Overall, we generated residential revenue growth of 5% this quarter, driven by an 11% increase in broadband revenues. We are very pleased that we have achieved superior market share in our incumbent markets where we have invested in fiber, and we are seeing strong broadband penetrations in our launched expansion markets.
In addition, we continue to drive faster speeds in our more rural incumbent markets by building to meet our A-CAM obligations and utilizing state broadband grants. In May, the SEC issued a notice seeking comment on a proposed extension of the A-CAM program, which we fully support. We anticipate an extension program would provide additional years of revenue support in exchange for deploying higher broadband speeds. We look forward to working through the comment process with the SEC and hope to have a final rule later this year. Extending the current federal A-CAM program first, and then pursuing BEAD Program funding would provide the best opportunities for TDS Telecom to take fiber deeper in communities.
Like LT, let me comment on the macroeconomic environment since that is top of mind for all of us. Inflation and supply chain challenges are concerning. However, we have been navigating these challenges successfully. And as a result, our strategic plans and guidance have not changed. Inflationary increases have been managed through a combination of price increases, process improvements and cost discipline. And like U.S. Cellular, many of TDS Telecom's contracts are long term with fixed pricing. To mitigate longer supply chain lead time, we have placed orders early and work with vendors to ensure our needed allotment of key components at acceptable prices. Therefore, we continue to be well positioned to manage -- managing these challenging economic conditions.
Turning to Slide 17. We highlight the achievements we've made this quarter. Year-to-date, we completed construction of 39,000 marketable fiber service addresses, deploying 17,000 in the quarter. We currently serve 34% of our total footprint with fiber. And as we have previously shared, we expect to serve approximately 60% of our total footprint with fiber by 2026. In line with our growth objectives, service addresses grew 7% year-over-year. In the second quarter, we increased our availability of 1 gig speeds to 63% of our total service addresses, up from 56% a year ago. We also continue to see positive trends in our broadband penetration rates for markets that have been fully launched for more than 12 months, and we still anticipate 40% to 50% consumer penetration in a steady state.
Our service address delivery is close to what we had planned for midyear. We're still working hard to reach our goal of 160,000 service addresses in 2022 with the expectation of ramping up in the second half of the year. As we previously mentioned, we continue to manage a variety of industry-wide headwinds, including inflation and supply chain as well as a variety of localized challenges such as permitting complexities and contractor labor shortages. We are pleased to have a broad pipeline of markets that give us flexibility in managing our bills. It's important to keep in mind that this is a long-term strategy. And although service address delivery might shift between years, we're still confident of meeting our goal of 1.2 million fiber service addresses by 2026.
On Slide 18, you can see the broadband connection growth across all markets. Total broadband residential connections grew 5% in the quarter as we continue to fortify our network with fiber and expand into new markets. We are on track in our network construction under the A-CAM program also helping to drive growth in our incumbent markets. Shown on the graph on the right, we continue to see demand for greater broadband speeds with 68% of our customers taking 100 megabit per second or greater, up from 63% a year ago. Our 1-gig product, along with our 2-gig product in certain markets, are important tools that will allow us to defend and win new customers. In areas where we offer 1-gig service, we are seeing 23% of our new customers taking this superior product.
Our focus on fast, reliable service has generated an 11% increase in total residential broadband revenue, which includes a cost recovery fee implemented in the second quarter for broadband subscribers.
On Slide 19, total operating revenues increased 2% year-over-year, largely driven by growth in residential revenues, which increased 5% across all markets. As shown in the chart on the left, expansion market revenues increased year-over-year following the timing of service address delivery. Residential wireline incumbent revenue increased 2% year-over-year due to price increases and growth in broadband connections, offset by a decline in video and voice connections. Likewise, cable residential revenues grew 3% due to a price increase and an increase in broadband connections, also partially offset by a decline in video connections.
Commercial revenues decreased 6% in the quarter primarily driven by lower CLEC connections, and wholesale revenues decreased 1%. Price increases and overall product mix changes drove a 3% increase in average residential revenue per connection.
Now let me sum up the combined financial results for the quarter as shown on Slide 20. As we just mentioned, revenues increased 2% from the prior year as growth from our fiber expansion an increase in broadband subscribers and average residential revenue per connection exceeded the declines we experienced in our legacy business. Cash expenses increased 4% year-over-year due to increases to support current and future growth, which is not yet reflected in our revenues. And as a result, adjusted EBITDA declined 2%. Capital expenditures increased 21% from last year as we continue to increase our investment in fiber deployment and focus on broadband growth.
Moving to Slide 21. We have presented guidance, which is unchanged from what we previously shared. We expect capital expenditures and expenses to ramp up in the second half of the year as we continue to progress on our fiber deployment in new markets, and we expect to end the year within the guidance range. I want to thank all of our associates for their dedication to the success of TDS Telecom. Our positive quarterly results are a product of your hard work. And with that, I look forward to updating you in the third quarter.
Now I'll turn the call back over to Colleen.
